Keysight Technologies E5071C to E5080B Code Migration

Configuration Guides

Overview

Switching from the E5071C to the E5080B simplifies complex measurements with integrated functionality and applications. You also get reliability and repeatability from best-in-class performance in dynamic range, trace noise, and frequency range.

Upgrading an instrument in your workflow doesn’t have to mean significant downtime to create SCPI commands all over again. The E5080’s Code Emulation Mode enables you to keep using your existing E5071C code. This document describes how to use the E5080B’s Code Emulation Mode as well as how to rewrite E5071C commands to run on the E5080B.

Part 1: Rewriting SCPI commands from E5071C to E5080B

This chapter describes how to migrate the E5071C’s remote control test program to the E5080B by rewriting the SCPI commands. The example program discussed here is a simple band pass filter test program. The overall flow of the example program is as follows;

  • Ch1: S11, S22, and S21 measurements in a wide span, linear sweep or segment sweep
  • Ch2: S11, S22, and S21 measurements in a narrow span, linear sweep
  • Plotting traces to two windows or four windows, as shown below
  • Setting limit lines and markers
  • Performing the 2-port full cal
  • Triggering the measurement and query the trace data
  • Saving & recalling state & user cal data

Marker setup

The following examples put the markers as follows, in the MKR coupling OFF mode;

Ch2 S11 measurement: MKR1 at 2.85 GHz

Ch2 S21 measurement: MKR1 at 2.75 GHz, MKR2 at 2.95 GHz

Ch2 S22 measurement: MKR1 at 2.85 GHz

Mechanical full 2-port cal

The following example performs the full 2-port (SOLT) cal using the E5071C’s commands. The calibration is performed for the channel-1 and 2 together in the same connections as follows;

Port-1 open cal for Ch1 & 2 → Port-1 short cal for Ch1 & 2 → … → Thru cal for Ch1 & 2 → Done.

The 85033D/E 3.5 mm mechanical cal kit is selected in this example.

Mechanical full 2-port cal, continued

The following example performs the same full 2-port cal using the E5080B’s guided cal commands. The connector type (of the cal kit and the DUT) and the cal kit’s model number must be specified with the string data for the analyzer ports to be used. With the unmodified default cal kit definition, the E5080B automatically performs the unknown thru cal (SOLR cal) for the test ports of the same connector gender like this example.

Mechanical full 2-port cal, continued

This is another example routine of the full 2-port cal utilizing the prompt string messages like “Connect 3.5 MM FEMALE OPEN to port-1” provided by the E5080B’s guided cal.

2-port ECal

The following example performs the 2-port ECal for the channel-1 and 2 on the E5071C. The calibration is performed with a defined thru. To perform the unknown thru ECal, the command “:SENS:CORR:COLL:ECAL:UTHRU:STAT ON” should be added
