in an error reported from processing the setup file

- Fix an issue with USB bus CRC calculation for a zero length data packet

v1.22 3/30/2016
- Added control for readout transparency

Defects Fixed:
- Fixed an issue with CAN bus and zoom with large numbers of packets
resulting in slow performance for pan across record
- Fix an issue where DVM DC Autorange would not settle properly
- Fixed "flicker" between RF manual and peak markers when they
- Fixed an issue with manual markers not displaying in the correct
location on Frequeny Domain Reference waveforms
- Fixed an issue with Peak markers not working if Stop Frequency was
greater than maximum frequency range
- Fixed an issue with recalling Frequeny Domain Reference waveforms
not drawing in the correct position
- Fixed an issue with channel 4 waveforms saving to Reference when
saving after a single sequence acquisition
- Fixed issue with frequency domain math waveforms being improperly
converted to dBm during save to .csv files
- Fixed issue with Save All with multiple frequency domain traces
causing overwritten data values
- Improved save operation where frequency domain waveforms are
- Fixed a case where frequency domain units did not match the saved
data by forcing all RF trace data to be saved as dBm
- Fixed an issue where RF saved setups would not properly recall
vertical units
- Fixed an issue with saved References not allowing very small
vertical scales
- Fixed a case where completing an acquisition with Roll Mode on
Long Records could result in the first portion of the waveform
being overwritten
- Fixed an issue with RMS measurement with vertical position moved
away from center screen
- Fixed an issue where measurements would not complete after undoing
an autoset
- Fixed an issue with NPULSECOUNT measurement type not counting
- Fixed an issue with immediate measurement on math when stopped
- Fixed a case where math units for absolute value were being cleared
- Fixed an issue with attachments for ePrint
- Fixed an issue with AC Coupled Trigger losing trigger with
vertical position changes
- Fixed an issue with a legacy command 'HARDCOPY STARt'
- Fixed an issue with where pan range was locked in zoom mode
- Fixed an issue where an Application Error could appear with Roll
Mode, 5M records, and HiRes acquisition modes. Under these
conditions, acquisition trigger mode is forced to Normal
- Fixed an issue with RF Pre-Amp always downloading cal constants
on attach
- Fixed an issue where RF Pre-Amp is in the wrong state on re-attach
- Fixed incorrect value displayed for digital sample rate
- Fixed an issue where Signal Path Compensation could fail if
run after Diagnostics. An instrument reboot is recommended after
running Diagnostics
- Improved edge trigger alignment for MagniVu on digital channels

Known Issues:
- Previewed spectrum data may save previewed header values instead of
acquired data. This can result in incorrect save file data.
To workaround: save frequency domain waveforms prior to
making changes to horizontal or vertical parameters

recalled using e*Scope or OpenChoice Desktop and a probe is attached
- Removed AFG keypad units selection for GHz and ps
- Improved instrument stability and signal path compensation (SPC)

v1.14 11/20/2014
