Firmware revision query
The instrument has three microprocessors for control of various internal systems.
Each plug-in module also has its own on-board microprocessor. You can query
the instrument and each module to determine which revision of firmware is
installed for each microprocessor.
– The instrument returns three revision numbers. The first number is the
firmware revision number for the measurement processor; the second is the
input/output processor; and the third is the front-panel display processor. For
each plug-in module, the instrument returns one revision number for the
on-board processor.
– Front-Panel Operation:
REV X.X-Y.Y-Z.Z (for 34970A)
REV X.XX-Y.YY-Z (for 34972A)
Turn the knob to read the firmware revision number for the module installed in
each of the three slots. If a slot does not contain a module, EMPTY SLOT is
displayed.
– Remote Interface Operation: Use the following command to read the system
firmware revision numbers (be sure to dimension a string variable with at least
40 characters).
*IDN?
The above command returns a string in the form:
Keysight Technologies,34970A,0,X.X-Y.Y-Z.Z
