I am programming with HP VEE ver 7.5. I have loaded the device drivers and eveything is communicating okay - as other programming functions are working just fine. I am having trouble locating the instruction for reading CHA & CHB display offsets via VXI Plug & Play. Test Set-up calibration has been performed and both offsets are enabled. The numerical values can be visually read from the power meter's front panel display. Do I have to use a Pass-through Function (or other)? Could someone provide me with an example? Pressed for time...
CALC1|2:GAIN[:MAGN] <numeric value> hpe4419_cmdReal
CALC1|2:GAIN[:MAGN]? [MIN|MAX] hpe4419_cmdString_Q
CALC1|2:GAIN:STAT <boolean> hpe4419_cmd
CALC1|2:GAIN:STAT? hpe4419_cmdInt16_Q
So, in VEE to set the display offset for channelA, you will use "Send Real" under the "Passthrough Functions" and in the sendRealCommand field you will use calc1:gain and under sendReal field you will use the offset value, for example, 10, for 10 dB offset.
