7.3.5 Programming the BIAS Voltage (VBIAS)
Command
Explanation
Response Example
Programming
":VBIAS:SET <NR3>"
Programs the bias voltage
":VBIAS:START <NR3>"
Programs the bias start voltage for “ELCH” *)
":VBIAS:STOP <NR3>"
Programs the bias stop voltage for “ELCH”
Reading
":VBIAS:SET?"
Reads the bias voltage
[:VBIAS:SET <NR3><LF>]
":VBIAS:MIN?"
Reads the allowed minimum bias voltage
[:VBIAS:MIN <NR3><LF>]
":VBIAS:MAX?"
Reads the allowed maximum bias voltage
[:VBIAS:MAX <NR3><LF>]
":VBIAS:MIN_W?"
Reads the minimum bias voltage for UBIAS - DAC = 0000
[:VBIAS:MIN_W <NR3><LF>]
":VBIAS:MAX_W?"
Reads the maximum bias voltage for UBIAS - DAC = FFFF
[:VBIAS:MAX_W <NR3><LF>]
":VBIAS:START?"
Reads the bias start voltage for “ELCH”
[:VBIAS:START <NR3><LF>]
":VBIAS:STOP?"
Reads the bias stop voltage for “ELCH”
[:VBIAS:STOP <NR3><LF>]
*) ELCH = ELectrical CHaracterization, a PRO8000 Macro Function. Please see the PRO8000 Series Mainframe
