5.2.7.1 Controls on the Gain Compression tab
Amplifier Compression/Setup Frequency Converting DUT
Opens the Multi-channel setup dialog for gain compression measurements:
●
See Chapter 5.2.7.2, "Amplifier Compression setup dialog", on page 394 for non-
frequency converting DUTs
●
See Chapter 5.2.7.3, "Converter Compression setup dialog", on page 395 for fre-
quency-converting DUTs
Compression Point Power In / Compression Point Power Out / Compression
Point S-Param
Selects the input power, output power, or transmission S-parameter value at the
<x dB> compression point as the measured quantity, where <x dB> is the specified
Compression Value.
Remote command:
'CALCulate<Ch>:PARameter:MEASure '<TraceName>', 'CmpPtPin' |
'CmpPtPout' | 'CmpPtS'
CALCulate<Ch>:PARameter:SDEFine '<TraceName>', 'CmpPtPin' |
'CmpPtPout' | 'CmpPtS'
Compression Value
With a "Compression Value" of x, the gain compression measurement searches for the
x dB compression points of the power sweeps.
The x dB compression point is defined as the stimulus level where the response value
has dropped by x dB compared to the response value at start power.
Remote command:
[SENSe<Ch>:]FREQuency:COMPression:POINt
Skip Linear Sweep Section
Activates/deactivates skipping "irrelevant" power sweep points, as described in "Skip-
ping the linear part" on page 392.
Remote command:
[SENSe<Ch>:]FREQuency:COMPression:SKIP
Start Before Cmp
If Skip Linear Sweep Section is active, then for the next frequency, after measuring at
start power, the firmware continues the power sweep "Start Before Cmp" to the left of
the "Compression Point Power In" determined for the previous frequency.
See "Skipping the linear part" on page 392.
Remote command:
[SENSe<Ch>:]FREQuency:COMPression:SKIP:OFFSet
