Keysight E8402A, E8404A C-Size Mainframes User and Service Guide 247Calibration and Performance Verification Calibrating and Verifying Performance7 Read the temperatures from all three sensors in all thirteen slots. Use thecommand:STAT:QUES:TEMP:LEV? OUTwhere x is the slot number 0 - 12Record these temperatures in the Performance Test Record Table.8 If you used the average of the 39 internal sensors (you did not use an externaltemperature sensor), read the calibration temperature with the command:CAL:VAL:TEMP?Record the value.This concludes the Temperature Monitor calibration procedure. Note anytemperature that is more than ±2 degrees off the expected value.Verification Procedure1 For Performance Verification, read the temperatures from all three sensors inall thirteen slots. Use the command:STAT:QUES:TEMP:LEV? OUTwhere x is the slot number 0 - 12Record these temperatures in the Performance Test Record Table. Noteany temperature more than ±2 degrees off the expected value.This concludes the Temperature Monitor verification procedure. Note anytemperature that is more than ±2 degrees off the expected value.Voltage Monitor Calibration & VerificationTo perform a complete Temperature Calibration or Verification, the mainframemust be in the following state:– The mainframe should be under normal use conditions. This means thattypical VXI modules (VXI modules used in your test system) should beinstalled in the mainframe.– Commands can be sent via the Enhanced Monitor’s RS-232 port orthrough a command module or embedded controller.– Calibration includes: Calculating A/D offset and gain for each of the sevenVXI power supplies and externally applied voltages. Externally measuredvoltages previously reported to the enhanced monitor throughCAL:VAL:VOLT are used for these calculations.
