Measurement times are measured using a single trace (S
21
) display and one average. The measurement speeds
for the communications band are measured in a 25 MHz band from 824 – 849 MHz. The typical measurement times
displayed are as follows:

Measurement frequency
Frequency range of measurement can be narrowed within the calibration range without recalibration.
range
CW mode permits single frequency measurements, also without recalibration. In addition, the system accepts N
discrete frequency points where 2 <N <1601.
Domains Frequency Domain, CW Draw, and optional High Speed Time (Distance) Domain
Formats
Log Magnitude, Phase, Log Magnitude & Phase, Smith Chart (Impedance), Smith Chart (Admittance), Linear Polar, Log
Polar, Group Delay, Linear Magnitude, Linear Magnitude and Phase, Real, Imaginary, Real & Imaginary, SWR, and Power
1601 maximum. Number of data points can be switched to a value of 801, 401, 201, 101, 51, 15, or 3 points without
Data points recalibration (if 1601 points were used in the calibration). In addition, the system accepts an arbitrary set of N discrete
data points where 2 ≤N ≤1601. CW mode permits selection of a single data point without recalibration.
Can be entered in time or in distance (when the dielectric constant is entered). Automatic reference delay feature adds the
correct electrical length compensation at the push of a button. Software compensation for the electrical length difference
Reference delay
between reference and test is always accurate and stable since measurement frequencies are always synthesized.
In addition, the system compensates reference phase delay for dispersive transmission media such as microstrip.
Alternate sweep
Allows the ability to decouple channel 1 and 2 from channel 3 and 4 for the following parameters: correction type,
start and stop frequencies, number of data points, markers, sweep time, averaging, smoothing, and IF bandwidth.
Twelve independent markers can be used to read out simultaneous measurement data. In alternate sweep mode there
Markers are sets of markers for each frequency sweep. In delta reference marker mode, any one marker can be selected as the
reference for the other eleven. Markers can be directed automatically to the minimum or maximum of a data trace.
Enhanced markers
Marker search for a level or bandwidth, displaying an active marker for each channel, and discrete or continuous
(interpolated) markers. Identifies the X dB bandwidth of amplifiers, filters, and other frequency sensitive devices.
Marker sweep Sweeps upward in frequency between any two markers. Recalibration is not required during the marker sweep.
Limit lines Either single or segmented limit lines can be displayed. Two limit lines are available for each trace.
Single limit readouts Interpolation algorithm determines the exact intersection frequencies of data traces and limit lines.
Segmented limit lines
A total of 20 segments (10 upper and 10 lower) can be generated per data trace. Complete segmented traces can
be offset in both frequency and amplitude.
Both single and segmented limits can be used for PASS/FAIL testing. PASS or FAIL status is indicated on the display
Test limits after each sweep. In addition, PASS/FAIL status is output through the rear panel I/O connector as selectable TTL levels
(PASS=0V, FAIL=+5V, or PASS=+5V, FAIL=0V).
Tune Mode optimizes sweep speed in tuning applications by updating forward S-parameters more frequently than
Tune mode reverse ones. This mode lets users select the ratio of forward sweeps to reverse sweeps after a full 12-term calibration.
The ratio of forward sweeps to reverse sweeps can be set anywhere between 1:1 to 10,000:1.
Power sweep measurements Both Swept Power Gain Compression and Swept Frequency Gain Compression modes are available.
Seven measurement sequences can be created, stored, edited, and run from the front panel. Sequences can include
Sequencing front-panel functions as well as user-definable control statements. Sequences can be run from either the unit front
panel, via GPIB, or from an AT-style keyboard plugged into the front panel.
