Remote command:
CALCulate<Chn>:LIMit:SOUNd[:STATe]
Clear Test
Resets the limit check results.
Remote command:
Global Check
Activates or deactivates the global limit check including upper/lower limits and ripple
limits. The global limit check is a composite limit check over all traces of the current
channel setup. The result of the global check appears in a popup box whenever
"Global Check" is selected.
●
"PASS" represents pass for all traces with enabled limit check. A trace without limit
lines or with disabled individual limit check always passes the global check.
●
"FAIL" means that the limit check for one or more traces failed.
Remote command:
TTL1 Pass / TTL2 Pass
Assigns the active trace to the low-voltage (3.3 V) TTL output signals at the Aux. Port
(see
Note:
Because the Aux. Port is not available for the R&S
ZNLE, the "TTL1 Pass" and
"TTL2 Pass" checkboxes are not available for these instruments.
Monitoring a single trace
If "TTL1 Pass" ("TTL2 Pass") is selected and the trace passes all active limit checks,
then the TTL signal is applied to pin 13 (pin 14) of the Aux. Port. If one of the limit
checks fails, then no TTL signal is generated.
Monitoring several traces
If a channel contains several traces, is possible to assign each of them to any TTL out-
put. The assignment divides the traces of the channel into four groups:
●
Not assigned to signal 1 or signal 2
●
Assigned to signal 1, but not to signal 2
●
Assigned to signal 2, but not to signal 1
●
Assigned to both signals
If several traces are assigned to a pass/fail signal, then the TTL signal is only gener-
ated if all traces are within their respective limits. It is switched off if one trace exceeds
those limits.
