Search for programmatic commands and queries - See Help/PI Command Search.
Bug fixes and other enhancements
--------------------------------
- 2X to >100X speedup of general purpose modulation analysis (Option 21). Specific speedup varies by analysis length and modulation type.
- MCPR display now supports measuring up to 999 channels.
- Timestamp values now support nsec resolution.
- 'Select Displays' dialog now also shows displays that are currently unavailable but can be purchased.
- Added user control to enable/disable display of the "Data from warm-up period" message shown during instrument warm-up.
- Programmatic commands added for LTE ACLR display (Option 28).
Known Issues
------------
- Mask Search 'Stop' action sometimes stops one acquisition after the event.
Workaround: Use Replay 'Previous' to back up one acquisition and see the event.
- Additional measurements may be added to the Pulse Table upon recalling a .setup or .tiq file that was saved prior to this release.
Workaround: Perform a main preset prior to recall. Re-save the file using this current release.
- The order in which selected measurements appear in the pulse table may not be consistent upon recall of a .tiq or .setup file - the order
presented may change depending on which measurements are selected prior to the recall.
- There is no limit to the number of pulses that can be analyzed by the pulse cumulative displays (Option 20). However, Pulse Trace, Pulse Table,
and Pulse Statistics Displays provide a control for 'Max number of pulses' which, if selected, will limit the number of pulses analyzed in
the current acquisition.
- The Traces toolbar may show with controls missing or stacked upon each other.
Workaround: Expand the display to full screen, or restart the SPECMONB application.

Version 3.6.0239 Date: July 31, 2015
-----------------------------------------------------------------------------
This release note summarizes new features, improvements and bug fixes contained in the above software release.
The current software for the SPECMONB series RTSAs is available at www.tektronix.com
Version 3.6.0239 adds the following functions.
- LTE™ analysis supporting 3GPP TS V12.5.0 (2014-09), FDD and TDD (Option 28)
Bug fixes and other enhancements
--------------------------------
- APCO Project 25 (Option 26):
a. C4FM Modulation Fidelity calculated based on standard recommended reference deviation.
b. Symbol Rate accuracy made granular.
c. Measurement BW (Meas BW) option linked correctly to the analysis module. For HCPM, though the Meas BW is always kept as Auto.
d. Marker correlation between frequency deviation vs time and Symbol table fixed.
- Bluetooth (Option 27) now Supports Bluetooth SIG v4.2 (Low Energy payload length -255 octets)
- Fixed Real-Time IQ data output scaling.
- Fixed frequency shift in DPX (real-time) display.
- Frequency mask trigger now works to -80 dBc.
Known Issues
------------
- LTE:
a. Cell ID detection might not be correct for over the air captures if the channel is not good.
b. Multiple Cell ID detection not supported.
c. The equalization provided in Constellation is based on PSS and can occasionally show a shifted SSS constellation when
the signal exhibits time varying behavior.
d. When LTE Constellation or LTE Channel Spectrum is open already and LTE ACLR display is added from LTE Analysis Measurements,
it could change the frame structure and bandwidth setting of LTE Constellation and LTE Channel Spectrum.
Workaround - It is recommended that LTE ACLR display be invoked only from Standard Presets. This also helps set the many options
in the Channels tab and the Offset & Limits tab appropriately.
- APCO P25:
a. HCPM demodulation algorithm shows failures when the frequency error is more than +/-650 Hz.
Workaround - The Center frequency has to be adjusted for correct demodulation in such cases.
b. SEM setups with very close offset regions (in the order of kHz) do not show correct results when operated in
swept mode (Real time check box disabled in parameters tab).
Workaround – Use SEM for P25 in Real time mode (Check box selected in parameters tab).
Workaround(2) - Add a Spectrum display and set the span similar to the SEM display.

Version 3.5.0134 Date: March 10, 2015
-----------------------------------------------------------------------------
This release note summarizes new features, improvements and bug fixes contained in the above software release.
The current software for the SPECMONB series RTSAs is available at www.tektronix.com
Version 3.5.0134 adds the following functions.
- Support for improved minimum signal duration for 100% probability of intercept for DPX spectrum and frequency mask trigger (Option 300 High Performance Real Time).
- Support for higher dynamic range for acquisition bandwidths greater than 40 MHz (Options B85HD, B125HD, B16xHD)
- Support for 125 MHz acquisition bandwidth (Option B125)
- Support for Bluetooth 4.1 analysis for Low Energy, Basic Rate and Enhanced Data Rate (Option 27)
Bug fixes and other enhancements
--------------------------------
- Fixed occasional analysis failure in Spectrum display when using large Span/RBW ratios.
- Fixed horizontal and vertical scaling inconsistencies for the 'Spur Search Multi Zone 9k-1GHz' Application Preset.
- Frequency Mask Trigger would not trigger until DPX spectrum display is opened.
- Double pressing keypad Freq, Span, RBW buttons prevents data entry.
- Unable to use keypad Hz key in Spurious measurement setting table.
- Audio measurement unstable with acquisition bandwidth less than or equal to 312.5 kHz.
- Uneven noise floor in wide spans. Now when measurment optimization mode is set to "Best for multiple displays",
the instrument sweeps in finer increments (less uneven noise floor). "Minimize sweep time" mode is unchanged.
Known Issues
------------
Bluetooth 4.1 analysis (Option 27):
- For Basic Rate, the analysis module will report the packet type and other header information appropriately. The Packet type
in summary is listed if the signal that is being analyzed is DH1/3/5, DM1/3/5 or EDR signals 2-DH1/3/5 or 3-DH1/3/5.
Although the Type field (4 bits) under Packet Header will show the correct 4 bit code, any other packet type apart from the ones
listed above will be shown as OTHERS.
Workaround – the 4 bit type field can be used to find the packet Type.
- The calculations shown in the display for Frequency Deviation vs time are white in color and do not show up properly
in Blizzard View.
Workaround – Use the ‘Classic’ color scheme for Frequency Deviation vs time.
P25 application (Option 26):
- Modulation Fidelity for P25 Phase 1 C4FM is now calculated with a fixed reference signal,instead of a recalculated reference
as it was in the prior releases.

Version 3.3.0201 Date: August 8, 2014
-----------------------------------------------------------------------------
This release note summarizes new features, improvements and bug fixes contained in the above software release.
The current software for the SPECMONB series RTSAs is available at www.tektronix.com
Version 3.3.0201 adds the following functions.
APCO P25 measurement application (Opt 26)
Noise Figure and Gain (Opt 14)
Mask compare/act (show violation, save data, save trace, save picture, alert)
Navigator view for Time Overview

shared location on screen for improved ease of use
Bug fixes and other enhancements
--------------------------------
- Improved layout and usability for Analysis and Spectrum time controls in Time Overview display.
- Vertical axis labels added to Spectrum, DPX Spectrum, Amplitude vs Time, and Time Overview displays.
- 'Top of screen' scale control removed from Spectrum, DPX Spectrum and Amplitude vs Time displays.
- Improved visibility of marker locations and readouts. Changed marker behavior such that reference marker readout
is always displayed in upper left and selected marker readout is always displayed in upper right of screen.
- Corrected Eye Diagram trace for APSK modulation analysis.
Known Issues
------------
- DPX Phase and Frequency: Vertical axis labels are shown in amplitude units rather than degrees or Hz.
Workaround: Use the vertical scale and position readouts and markers to determine the signal phase and frequency values.
- Vertical axis labels may all show 0.0 for some scales in linear units due to insufficient readout resolution.
- P25: Symbol table display may not show results values.
Workaround: Change display dimensions, maximize/minimize display, add/remove other displays.
- P25: Summary display/Frequency Deviation results do not employ an FM Demodulator BW between 3 and 15 kHz as specified
in the standard.
Workaround: Measure frequency deviation using the Analog Modulation/FM measurement display with the Measurement BW set appropriately.
- P25: The Transient Frequency behavior measurement in P25 Freq Dev vs Time display will show mean frequency deviation > 12.5 kHz
as failure in t1 and t3 regions. The standard specifies this comparison for Pass/Fail to be done only when the output power rating
is more than 6 Watts.
Workaround: Ignore the pass/fail results for this measurement if the radio output power rating is < 6 Watts.
- P25: Programmatic commands for Pass/Fail results in the P25 Summary display are not available.
- Noise Figure and Gain: Adding a new display from the Noise Figure and Gain folder invalidates the Noise Figure/Gain calibration.
Workaround: Select all required Noise Figure and Gain displays prior to performing the Noise Figure/Gain calibration. Use
the display Maximize and Restore Down buttons to show/hide displays.
- Noise Figure and Gain: Changing 'Loss @ DUT Input' value shows that the Noise Figure/Gain cal is invalid but
it is actually still valid.
Workaround: Set the 'Loss @ DUT Input' value prior to performing the Noise Figure/Gain calibration.
- Mask Test: No control available for setting basename for saved files.
Workaround: Save a trace, picture, or acquisition data file to set the file basename prior to enabling Mask Test.
- Mask Test: Programmatic commands to save/load masks work for only the new .msk file format - the older .csv format is not
supported.
Workaround: Convert .csv mask files to .msk format.
