Note: In remote control, the ripple limit check result is calculated once at the end of
each sweep. If the ripple limits are changed, a new sweep is required to obtain upda-
ted ripple limit check results. In single sweep mode (INITiate<Ch>:CONTinuous
OFF), the new sweep must be started explicitly. This behavior is different from manual
control where a changed ripple limit line can directly affect the pass/fail result of the
displayed trace.
Suffix:
<Chn>
.
Channel number used to identify the active trace
<Seg> Number of the ripple limit range.
Example:
*RST; CALC:RIPP:DATA 1, 1500000000, 2000000000,
3
Define and enable a ripple limit range in the stimulus range
between 1.5 GHz and 2 GHz, assigning a ripple limit of +3 dB.
CALC:RIPP:STAT ON; SEGM:RES?
Enable the limit check and query the result for the created
range. Possible response: 0,0.3529814004.
CALC:RIPP:DATA 0, 2500000000, 3000000000, 3
Define a second ripple limit range with disabled limit check (no
limit check results are displayed in the diagram area).
CALC:RIPP:SEGM2:RES?
Query the result for the second range. Possible response:
0,1.149071925.
Usage:
Query only
Manual operation: See "Ripple Check" on page 352
CALCulate<Chn>:RIPPle:SEGMent<Seg>:STIMulus:STARt <FreqPowTime>
CALCulate<Chn>:RIPPle:SEGMent<Seg>:STIMulus:STOP <StimValue>
These commands change the start or stop stimulus values (i.e. the smallest or largest
stimulus values) of a ripple limit range. A range must be created first to enable these
commands (e.g CALCulate<Chn>:RIPPle:DATA). See Chapter 5.4.1.2, "Rules for
Ripple Test Definition", on page 138.
Tip: To define several ripple limit ranges with a single command, use
CALCulate<Chn>:RIPPle:DATA.
Suffix:
<Chn>
.
Channel number used to identify the active trace
<Seg> Number of the ripple limit range.
Parameters:
<StimValue> Stimulus values (unitless) confining the ripple limit range.
The unit is adjusted to the sweep type of the active channel
([SENSe<Ch>:]SWEep:TYPE).
Range: Virtually no restriction for ripple limit ranges.
*RST: n/a (no ripple limit line defined after a reset)
Default unit: NN
