other five. Markers can be directed automatically to the minimum or maximum of a data trace.

Enhanced Markers: Marker search for a level or band- width, displaying an active marker for each channel, and discrete or continuous (interpolated) markers.

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 deter- mines the exact intersection frequencies of test data and limit lines.

Segmented Limit Lines: A total of 20 segments (10 up- per and 10 lower) can be generated per data trace. Com- plete segmented traces can be offset in both frequency and amplitude.

Test Limits: Both single and segmented limits can be used for PASS/FAIL testing. The active channel’s PASS or FAIL status is indicated on CRT after each sweep. In addi- tion, 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: Tune Mode optimizes sweep speed in tun- ing applications by updating forward S-parameters more frequently than reverse ones. This mode allows the user to 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.

DISPLAY CAPABILITIES

Display Channels: Four, each of which can display any S-parameter or user defined parameter in any format with up to two traces per channel for a maximum of eight traces simultaneously. A single channel, two channels (1 and 3, or 2 and 4), or all four channels can be displayed simulta- neously. Channels 1 and 3, or channels 2 and 4 can be overlaid.

LCD: Color, 8.5-inch diagonal.

Trace Color: The color of display traces, memory, text, markers and limit lines are all user definable.

Trace Overlay: Displays two data traces on the active channel’s graticule simultaneously. The overlaid trace is displayed in yellow and the primary trace is displayed in red.

Trace Memory: A separate memory for each channel can be used to store measurement data for later display or subtraction, addition, multiplication or division with current measurement data.

Scale Resolution (minimum):

Log Magnitude: 0.001 dB/div

Linear Magnitude: 1 pU

Phase: 0.01o

Group Delay: 0.001 ps

Time: 0.001 ms

Distance: 0.1 ∝ m

SWR: 1 pU

Power: 0.05 dB

Autoscale: Automatically sets Resolution and Offset to fully display measurement data.

Reference Position: Can be set at any graticule line.

Annotation: Type of measurement, vertical and horizon- tal scale resolution, start/stop or center/span frequencies, and reference position.

Blank Frequency Information: Blanking function re- moves all references to displayed frequencies on the CRT. Frequency blanking can only be restored through a system reset or GPIB command.

MEASUREMENT ENHANCEMENT

Data Averaging: Averaging of 1 to 4096 averages can be selected. Averaging can be toggled on/off with front panel button. A front panel button turns data averaging on/off, and a front panel LED indicates when averaging is active.

Video IF Bandwidth: Front panel button selects four levels of video IF bandwidth. MAXIMUM (10 kHz), NOR- MAL (1 kHz), REDUCED (100 Hz) and MINIMUM (10 Hz). Trace Smoothing: Functions similarly to Data Averaging but computes an average over a percentage range of the data trace. The percentage of trace to be smoothed can be selected from 0 to 20% of trace. Front panel button turns smoothing on/off, and front panel LED indicates when smoothing is active.

SOURCE CONTROL

Frequency Resolution: 1 kHz (1 Hz standard on RF units and optional on Microwave units - Option 10A) Source Power Level: The source power (dBm) may be set from the 373XXA front panel menu or via GPIB. Refer to Level Control Range table on next page.

In addition, the port 1 power may be attenuated in 10 dB steps, using the internal 70 dB (60 dB for 37397A) step at- tenuator. Similarly, high input signals into port 2, not ex- ceeding 1 watt, can be attenuated up to 40 dB, using the internal port 2 step attenuator.

Power Accuracy: ￿0.5 dB at 2 GHz at default power.

Power Meter Correction: The 373XXA offers a user-selectable feature that corrects for test port power variations and slope (on Port 1) using an external Hewle- tt-Packard 437B or Anritsu ML8403 power meter. Power meter correction is available at a user-selectable power level, if it is within the power adjustment range of the inter- nal source. Once the test port power has been flattened, its level may be changed within the remaining power ad- justment range of the signal source.

Set-On Receiver Mode: The 373XXA can be configured to measure the relative harmonic level of test devices with Set-On Receiver Mode capability. The 373XXA’s unique
