R&S FSP Remote Control – Description of Commands
CALCulate Subsystem
6.72 Operating Manual 1164.4556.12 - 06
CALCulate<1|2>:MARKer<1...4>:FUNCtion:POWer:RESult? ACPower | AOBandwidth |
AOBWidth | CPOWer | MCACpower | OBANdwidth | OBWidth | CN | CN0
This command queries the result of the power measurement performed in the selected window.
If necessary, the measurement is switched on prior to the query.
The channel spacings and channel bandwidths are configured in the
SENSe:POWer:ACHannel
subsystem.
To obtain a valid result, a complete sweep with synchronization to the end of the sweep must be
performed before a query is output. Synchronization is possible only in the single-sweep mode.
Parameters:
The parameters CN and CN0 are available from firmware version 1.40.
ACPower: adjacent channel power measurement
Results are output in the following sequence, separated by commas:
1. Power of transmission channel
2. Power of lower adjacent channel
3. Power of upper adjacent channel
4. Power of lower alternate channel 1
5. Power of upper alternate channel 1
6. Power of lower alternate channel 2
7. Power of upper alternate channel 2
The number of measured values returned depends on the number of adjacent/
alternate channels selected with
SENSe:POWer:ACHannel:ACPairs
.
With logarithmic scaling (RANGE LOG), the power is output in the currently
selected level unit; 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.
AOBandwidth |
AOBWidth Measurement of occupied bandwidth, all results. The results include the left and
right frequency/level information
Results are output in the following sequence, separated by commas:
1. Occupied bandwidth in Hz
2. T1 marker position in Hz (left marker)
3. T1 marker level
4. T2 marker position in Hz (right marker)
5. T2 marker level
Note:
The Occupied Bandwidth is marker position T2 - T1
CPOWer: Channel power measurement
With logarithmic scaling (RANGE LOG), the channel power is output in the cur-
rently selected level unit; with linear scaling (RANGE LIN dB or LIN %), the chan-
nel power is output in W.
