[SENSe<Ch>:]SWEep:AXIS:POWer <Scale>
Selects either the channel base power or one of the port powers as the stimulus axis in
all diagrams of the active recall set. This command has no effect if no port-specific
powers are defined.
Suffix:
<Ch>
.
Channel number
Parameters:
<Scale> String parameter, one of the following signals:
'Channel Base; Source' - base channel power
'Port p; Source' - source power at port p
'Port p; Phys' - source power at port p, including mechanical
source attenuation
'Gen g; Source' - source power at external generator g
*RST: 'Channel Base; Source'
Example:
*RST; SOUR:POW 5
Define a base channel power of +5 dBm. This power is also
used as an (initial) power for all test ports and external genera-
tors.
SOUR:POW1:OFFS -5, CPAD
Change the source power at test port no. 1 to 0 dB without
affecting the power at the remaining ports.
SWE:AXIS:POW 'Port 1; Source'
Select the source signal at port 1 as the reference signal for
power definitions.
SOUR:POW -5
Shift all powers by -5 GHz.
SWE:AXIS:POW 'Port 2; Source'
Select the source signal at port 2 as the reference signal for
power definitions.
SOUR:POW?
Query the power at test port 2. The response is 0.
Manual operation:
See "Stimulus Axis – Frequency / Power" on page 524
[SENSe<Ch>:]SWEep:COUNt <Sweep>
Defines the channel-specific number of sweeps to be measured and buffered in single
sweep mode (INITiate<Ch>:CONTinuous OFF). Use [SENSe:]SWEep:COUNt:
ALL to define the sweep count for all channels.
If controlled timing is active (INITiate<Ch>:CTIMing ON), then also in continuous
sweep mode (INITiate<Ch>:CONTinuous ON) this setting defines the number of
sweeps to be buffered (ring buffer).
Suffix:
<Ch>
