Performance Tests
Introduction
This section provides the test procedures used to verify that the 4339B’s specifications
listed in Chapter 8, General Information, of this manual are met. All tests can be performed
without access to the interior of the instrument. The performance tests can also be used to
perform incoming inspection, and to verify that the 4339B meets its performance
specifications after troubleshooting or adjustment. If the performance tests indicate that the
4339B is NOT operating within the specified limits, check your test setup, then proceed
with troubleshooting if necessary.
NOTE
Allow the 4339B to warm up for at least 30minutes before you execute any of the
performance tests.
NOTE
Perform all performance tests in ambient conditions of 23
°
C
±

≤
70% RH.
Test Equipment
Table 1 lists the test equipment required to perform the tests described in this section. Use
only calibrated test instruments when performance testing the 4339B4. Equipment which
equals or surpasses the key required specifications of the recommended equipment may be
used as a substitute.
Calculation Sheet
The calculation sheet is used as an aid for recording raw measurement data, and for
calculating the performance test results.
The performance test procedure gives the test sequence for performing a test. The complete
set of measurement data is recorded on the calculation sheet. The results are calculated
using the equations given on the calculation sheet, and the result are transcribed to the
performance test record.
The procedure for using the calculation sheet is:
1. Photocopy the calculation sheet.
2. Follow the performance test procedure and record the measurement value(s), the
4339B’s reading, etc., into the specified column on the calculation sheet.
3. Calculate the test result using the appropriate equation given on the calculation sheet,
and record the test result into the Test Result column of the performance test record.
