CALCulate:AVERage:COUNt?
Description Retrieves the number of measurements taken during a statistics operation.
This value is cleared whenever the Meter is powered off then back on, a
statistics function is enabled, or the Meter receives a reset through the
remote interface. This setting is stored in volatile memory.
Query CALC:AVER:COUN? Returns the count value of the statistics operation.
CALCulate:NULL:OFFSet(?) {<value>|MINimum|MAXimum}
Description Sets the offset value used for the zero function. Math operation must be
enabled to write to the zero offset register. This setting is stored in volatile
memory.
Parameters <value> = 0 to 120 % of highest range.
MINimum Sets offset register to -120 % of highest
range of selected function.
MAXimum Sets offset register to 120 % of highest range
of selected function.
Examples CALC: NULL:OFFS 100 Sets zero offset register to 100.
Query CALC:NULL:OFFS? Returns the zero offset register value.
CALCulate:DB:REFerence(?) {<value >|MINimum|MAXimum}
Description Sets the relative value used for the dB function. Math operation must be
enabled to write to the dB relative register. This setting is stored in volatile
memory.
Parameters <value> = 0 to ±200 dBm.
MINimum Sets dB relative register to -200 dBm.
MAXimum Sets dB relative register to 200 dBm.
Examples CALC:DB:REF 25 Sets dB relative register to 25 dBm.
Query CALC:DB:REF? Retrieves the dB relative register value.
CALCulate:DBM:REFerence(?) {<value>|MINimum|MAXimum}
Description Sets the reference impedance for the dBm function. Math operation must
be enabled to write to the dBm reference impedance register. This setting is
stored in volatile memory.
Parameters <value> = 2, 4, 6, 16, 50, 75, 90, 93, 100, 110, 124, 125, 135, 150, 250,
300, 500, 600 (default), 800, 900, 1000, 1200, or 8000
Ω .
MINimum Sets dBm reference impedance register to
50 Ω.
MAXimum Sets dBm reference impedance register to
8000 Ω.
Examples CALC:DBM:REF 110 Sets dBm reference impedance register to
110 Ω.
Query CALC:DBM:REF? Retrieves the present dBm reference impedance
register value.
CALC:DBM:REF? MIN Returns 50
CALC:DBM:REF? MAX Returns 8000
