Number of Display Measurements
Two measurement displays are available. Each measurement can have independent
instrument sweep and control parameters (including frequency settings, IF bandwidth,
power level, number of trace points, averaging, format, and scale). The instrument can
display a single measurement or dual measurements, on a split (two graticules) or overlaid
(one graticule) screen.
Measurement Choices
• Narrowband:
ET models: reflection (A/R), transmission (B/R), A, B, R
ES models: S
11
(A/R), S
22
(B/R), S
21
(B/R), S
12
(A/R), A, B, R
• Broadband: X, Y, Y/X, X/Y, Y/R*, power (B*, R*), conversion loss (B*/R*)
NOTE: X and Y denote external broadband-detector inputs; * denotes internal broadband
detectors.
Formats
• rectilinear: log or linear magnitude, SWR
• phase, group delay, real and imaginary, Smith chart, and polar
Trace Functions
The analyzer can display current-measurement data, memory data or
current-measurement with memory data simultaneously. Division of
current-measurement data by memory data is also available.
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.
