Meas Setup
Preset
Limit 1, not affected by Mode Preset, preset by Restore Mode Defaults.
State Saved
Saved in instrument state.
Initial S/W Revision
A.02.00
Limit
Selects whether the limit and margin are displayed. If Test Limits is on, this also determines
whether the test trace (see
) will be tested against the limit. If Limit On/Off
is On, the following occurs:
l
The limit line is displayed, in the same color as the limited trace, but paler. Portions of traces
which fail the limits will be displayed in red.
l
The margin line is displayed if Margin is on and the Margin Value is non-zero (see
). The margin line is displayed in the same color as the limit line, but paler still and
dashed. Portions of traces which pass the limits but fail the margin will be displayed in
amber.
l
The trace is tested for the purpose of the “Trace Pass/Fail” indication in the graticule if, in
addition to Limit On/Off being On, the trace is displayed and Test Limits (All Limits) is on (see
). If the trace is not tested, no report of the trace passing or failing
is seen on the graticule. Note that the SCPI queries of Limit Pass/Fail are independent of
these conditions; the test is always performed when queried over SCPI.
The PASS/FAIL box in the corner of the Meas Bar is only displayed if there is at least one “Trace
Pass/Fail” indication displayed in the graticule.
Note that the red and amber coloring of traces which fail the limits and/or margins only applies to
traces whose X-axis corresponds to the current analyzer X-axis. Traces which are not updating
(in View, for example) will not change color if the analyzer X-axis settings (e.g., start and stop
frequency) do not match those of the trace, for example if they have been changed since the trace
stopped updating. In this case, the Invalid Data indicator (*) will appear in the upper right hand
corner.
When the limits are frequency limits but the trace is a zero-span trace, the limit trace is drawn at
the limit amplitude of the center frequency. When the limits are time limits but the trace is a
frequency domain trace, the limit trace is drawn according to the current time axis, with the left
of the screen being 0 and the right being equal to sweep time.
