Alphabetical Command Reference
LIM
LIM
Syntax
LIM<D|L|M|S|U><num>[DB|HZ];
Description
These commands edit a limit test segment. The limit table editing is begun with
EDITLIML;
, and a segment is brought up for editing with
SEDI<num>;
or added using
SADD;
. The segment is closed with
SDON;
, the table is closed with
EDITDONE;.
NOTE Currently these commands can be queried by sending the command followed
by the
OUTPACTI
command, as in the following example to query the upper
limit value:
10 OUTPUT 716;”LIMU;OUTPACTI;”
Future revisions of firmware may support the standard query form (which
currently always returns a zero) for these commands.
Command Description Range Query Response
LIMD Sets the limit delta value while editing a
limit line segment.
amplitude range
1
1. For log mag:
±
500 dB. For phase:
±
500 degrees. For Smith chart and Polar:
±
500 units. For linear magnitude:
±
500 units. For SWR:
±
500 units. The scale is always positive, and has minimum values of 0.001 dB, 10e-12
degrees, 10e-15 seconds, and 10 picounits.

2. For frequency or power sweeps, refer to “Preset State and Memory Allocation,” in your analyzer’s reference
guide. For CW time: 0 to 24 hours. For frequency sweep, transform on:
±
1/frequency step. For CW time sweep,
transform on:
±
1/time step.
