TBS1000 Series Oscilloscope Customer Release Notes Version: [26.02] Last revised: [July 22, 2013] Product: TBS1000 Introduction ----------------------- Version v26.02 is a firmware update for the TBS1000 Series oscilloscope. Installation Guide ----------------------- This firmware update is intended to update TBS1000 Series oscilloscopes to version v26.02. History ----------------------- v26.02 July 22, 2013 1) support for five TBS1K models: TBS1022, TBS1042, TBS1062, TBS1102, TBS1152. Users who would like to disable Autoset and Autorange, read the following: (1) Via Programmatic Interface Programmatic Interface commands are AUTOSET:ENABLE? and AUTOSET:ENABLE {ON, OFF, 0, 1} (2) Via Front Panel Using Front Panel Control feature can only be accessed when in service mode. Please see service manual for instructions on how to access service mode. Once in service mode, press UTILITY button, then select "Service" option, then select "Service Diag." option, then select "page 2 of 2", then select "AUTOSET ENABLE" to be either 0 or 1. 0 = disabled and 1 = enabled. ************ Users who program their own custom application software to communicate with the TBS1000 should read the following: For optimal performance, when programming and communicating to the instrument the following is recommended: (1) Be familiar with the programmers guide Status and Events section. (2) Configure the rear USB port on instrument to "Computer" or "Auto Detect" setting. Press the UTILITY button. Select "Options" option. Change the "Rear USB Port" option to "Computer" or "Auto Detect" (3) Controlling programs should use the *STB? query in preference to the serial poll following a service request (SRQ). Why?: A serial poll following a service request (SRQ) may cause communication to hang. (4) Connect the TBS1000 to a USB 2.0 port for reliable communication. Why?: When connected to a USB1.0 or USB1.1 port, data communication to the TBS1000 is unreliable. The problem is magnified when communicating through a hub or when multiple instruments are connected to the PC. (5) Programs should check for a timeout error after each read. Why?: In rare circumstances, the read following a query may time out. When a timeout error is observed, it is necessary to re-send the query and re-read the query response. ********************************************************************* The following only apply if using a TEK-USB-488 adapter ********************************************************************* (6) When instrument is communicating via a TEK-USB-488 GPIB to USB adapter, *WAI command, the BUSY? query, and the *OPC? query are preferred methods of achieving synchronization. See the programmer manual for examples of how to use these methods. Why?: The TEK-USB-488 adapter is unreliable when receiving service requests (SRQs) from TBS1000. Following is a recommended programming example for how to determine when a command has been executed by the instrument. *SRE 0 # Disable service request :ACQUIRE:STOPAFTER SEQUENCE set timeout to a value greater than that expected for the command to complete :ACQUIRE:STATE B; *OPC? (7) When instrument is communicating via a TEK-USB-488 GPIB to USB adapter, the following hardcopy file formats are recommended: BMP, EPSIMAGE, JPEG, RLE, TIFF. (Do not use PCX). (8) Refer to the firmware release notes for the TEK-USB-488 adapter, for programming recommendations generic to the adapter. ======================== END ===========================
