17. Power of upper alternate channel 1
18. Power of lower alternate channel 2
19. Power of upper alternate channel 2
The number of measured values returned depends on the number of
carrier signals and adjacent/alternate channels selected with
SENSe:POWer:ACHannel:TXCHannel:COUNt and
SENSe:POWer:ACHannel:ACPairs.
If only one carrier signal is measured, the total value of all carrier signals
will not be output.
With logarithmic scaling (RANGE LOG), the power is output in dBm;
with linear scaling (RANGE LIN dB or LIN %), the power is output in W.
If SENSe:POWer:ACHannel:MODE REL is selected, the
adjacent/alternate-channel power is output in dB.
OBANdwidth | OBWidth
Measurement of occupied bandwidth
The occupied bandwidth in Hz is returned.
CN
Measurement of carrier-to-noise ratio
The carrier-to-noise ratio in dB is returned.
CN0
Measurement of carrier-to-noise ratio referenced to 1 Hz bandwidth.
The carrier-to-noise ratio in dB/Hz is returned.
Example of channel/adjacent-channel power measurement:
"SENS2:POW:ACH:ACP 3" 'Sets the number of adjacent/alternate channels in
screen B to 3.
"SENS2:POW:ACH:BAND 30KHZ"
'Sets the bandwidth of the transmission channel to 30 kHz.
"SENS2:POW:ACH:BAND:ACH 40KHZ"
'Sets the bandwidth of each adjacent channel to
40 kHz.
"SENS2:POW:ACH:BAND:ALT1 50KHZ"
'Sets the bandwidth of each alternate channel to
50 kHz.
"SENS2:POW:ACH:BAND:ALT2 60KHZ"
'Sets the bandwidth of alternate channel 2 to 60 kHz.
"SENS2:POW:ACH:SPAC 30KHZ"
'Sets the spacing between the transmission channel
and the adjacent channel to 30 kHz, the spacing
between the transmission channel and alternate
channel 1 to 60 kHz, and the spacing between the
transmission channel and alternate channel 2 to 90 kHz.
"SENS2:POW:ACH:SPAC:ALT1 100KHZ"
'Sets the spacing between the transmission channel
and alternate channel 1 to 100 kHz, and the spacing
between the transmission channel and alternate
channel 2 to 150 kHz.
"SENS2:POW:ACH:SPAC:ALT2 140KHZ"
'Sets the spacing between the transmission channel
and alternate channel 2 to 140 kHz.
"SENS2:POW:ACH:MODE ABS"
'Switches on absolute power measurement.
"CALC2:MARK:FUNC:POW:SEL ACP" 'Switches on the adjacent-channel power measurement
in screen B.
"INIT:CONT OFF"
'Switches over to single-sweep mode.
"INIT;*WAI"
'Starts a sweep and waits for the end of the sweep.
"CALC2:MARK:FUNC:POW:RES? ACP"
'Queries the result of adjacent-channel power
measurement in screen B.
"SENS2:POW:ACH:REF:AUTO ONCE"
'Defines the measured channel power as the
reference value for relative power measurements.
