Input impedance sets the impedance of the measurement system, used in power and ape measurements.
Allowed values are 50 or 75 (Ohms).
The query option returns the current setting.
POD either 50, 75 or HI.

iSTATe on[OFF|1]0
_ This command is.used to configure and make a Vector Voltmeter measurement (or measurements) and return the
result(s). Default is AVOLtage.
Options for <meas> are listed below
AVOL tage Channel A Voltage, using current setting of FORMat (LOG|LIN).
BVOLtage Channel B Voltage, using current setting of FORMat (LOG|LIN).
APOWer Channel A Power, using current settings of INPut:IMPedance and
FORMat (LOG|LIN).
BPOWer Channel B Power, using current ne of INPut:IMPedance and
FORMat (LOG|LIN).
BA B/A Magnitude Ratio, using current sete of FORMat (LOG[LIN).
PHASE B-A Phase.
. TRANsmission B/A Magnitude Ratio and B-A Phase, computed from the same
measurement, using current settings of FORMAT (LOG|LIN and POL[RECT)..
DELay Delay
SUR Standing Wave Ratio
RHO ; Reflection Coefficient, using current settings
FORMat (LOG|LIN and POL{RECT).
Y Admittance (1/2), using current settings of INPut:IMPedance and
FORMAT (POL|RECT).
2 . Impedance, using current settings of INPut: IMPedance and
FORMAT (POL[RECT).
CORE All basic measurements - AVOLtage, BVOLtage and PHASE.
Equivalent to MEAS? AVOL,BVOL,PHASE.
MEASure :TIMEout allows the measurement to timeout if the instrument has not locked
to a signal. The range of the timeout is 0 to 30-seconds. The default is 30 seconds.
MEASure :TIMEout: STATe defines if the timeout dinctton is in use. It sets the timeout
function to ON (1) or OFF (0).
The query option returns 1 or 0.
All the above measurements are also dependant on whether CORRection:STATe is ON or OFF.
