Display Annotations
Analyzer display annotations include start/stop, center/span, or CW
frequency, scale/division, reference level, marker data, softkey labels,
warning and caution messages, screen titles, time and date, and pass/fail
indication.
Limits
Measurement data can be compared to any combination of line or point
limits for pass/fail testing. User-defined limits can also be applied to an
amplitude- or frequency-reference marker. A limit-test TTL output is
available on the rear panel for external control or indiction. Limits are
only available in rectilinear formats.
Data Markers
Each measurement channel has eight markers. Markers are coupled
between channels. Any one of eight markers can be the reference marker
for delta-marker operation. Annotation for up to four markers can be
displayed at one time.
Marker Functions
Markers can be used in absolute or delta modes. Other marker functions
include: mkr
→
center, mkr
→
reference, mkr
→
electrical delay, searches,
tracking, and statistics. Marker searches include: mkr to max, mkr to
min, mkr
→
target, mkr bandwidth, notch, multi-peak, and multi-notch.
The marker-tracking function enables continuous update of marker
search values on each sweep. Marker statistics enable measurement of
the mean, peak-to-peak, and standard deviation of the data between two
markers. For rapid tuning and testing of cable-TV broadband amplifiers,
slope and flatness functions are also available.
