Overview of Performance Tests
In this chapter you will learn about all available performance tests as well as how to run the Service Support
Software to test and verify the performance of the Agilent E4438C ESG vector signal generator. These
performance tests verify that the signal generator meets specifications.
Chapter 1, “Getting Started,”
explains how to set up the Service Support Software for a particular set of test instruments and interfaced
components in a test environment.
Recommended Calibration Cycle
This instrument requires periodic verification of performance. Under normal use and environmental
conditions, the instrument should be calibrated every two years. Normal use is defined as about 2,000 hours
of use per year.
Performance Test Records
Unless stated differently, the Service Support Software for the Agilent E4438C ESG vector signal generator
can print a test record that contains the results of the automated performance tests. A performance test
record (located at the end of this chapter) can be photocopied for use when performing each of the two manual
performance tests for this product.
Recommended Test Equipment
The recommended test equipment table, located in Chapter 2, “Required Equipment,” on page 2-1 is the
complete list of equipment required to perform the procedures in this chapter. Test equipment is also listed
with each test and is shown in the test setup. However, to avoid clutter in the figures, the controller required
to run the Service Support Software is not shown in the test setup for each automated test. The controller
must be connected via GPIB to all of the test equipment in the currently selected automated tests. For
performance tests, other equipment can be substituted for the recommended models if it meets or exceeds the
critical specifications listed in
Chapter 2, “Required Equipment,” on page 2-1 For the adjustment procedures,
no equipment substitutions are available.
CAUTION In all test equipment configurations, cables and adapters need to be properly torqued.
Exceeding recommended torque values may cause damage to a cable or adaptor and may cause
inaccurate test results.

Connector Type Torque Value
APC 3.5 Use an Agilent 8710-1765 at 8-lb inch when
connecting APC 3.5 (m) to APC 3.5 (f).
SMA Use an Agilent 8710-1765 at 8-lb inch when
connecting APC 3.5 (m) to SMA (f).
Use an Agilent 8710-1582 at 5-lb inch when
connecting SMA (m) to APC 3.5 (f).
Type-N Type-N connectors may be connected finger tight. If a
torque wrench is used, Agilent 8710-1766 at 12-lb.
inch is recommended.
