Remote Operation
Manual 20791, Rev. C, June 2001 3-31
The LIMIT modifier reads the PASS/FAIL status of a limit line test. This command
assumes that a limit line has been previously defined and turned on (see SWP command,
LIMIT modifier). When this command is received, the analyzer will read the PASS/FAIL
status of the indicated channels limit line test and wait to be talk-addressed by the control-
ler. When talk-addressed, the analyzer will return the string PAS S or FAIL according to the
results of the limit line test (PASS indicates that the channel’s trace was within the limits,
FAIL indicates outside the limits).
Modifier name: LIMIT
Modifier syntax: LIMIT
return data format: PASS or FAIL
This modifier is to request that the power be measured at the cursor position (assumes
channel is in swept mode and that the cursor is turned on). The data returned will be in the
following format:
cursor data = freq, data EOL
freq = F
data =
±
D
where F is a variable field number with three digits to the right of the decimal point in MHZ,
and D is a variable field number with three digits to the right of the decimal point in dBm or
dB.

The second form of the OP command sends TRACE, PATHCAL, or CALFACTOR data
from the 8003 to the controller. The data format is as follows:
