Performance Tests
The procedures in this section test the Agilent 83438A’s performance using
the specifications listed in Chapter 3, “Specifications and Regulatory Informa-
tion” as the performance standard. All of the tests are done manually without
the aid of a computer. None of these tests require access to the interior of the
instrument. Allow the Agilent 83438A to warm up for 15 minutes before doing
any of the performance tests.
Test 1. Total Output Power 5-21
Test 2. Power Stability 5-22
Calibration Cycle
This instrument requires periodic verification of performance. The instrument
should have a complete verification of specifications at least once every two
years.
CAUTION
Option 022 instruments have an angled-fiber output. Be sure to use an angled-
fiber patchcord during testing. If you do not have an angled-fiber patchcord
available, you can purchase the required accessories from Agilent
Technologies. These include the Agilent 81000SI DIN connector interface and
the Agilent 81113PC DIN 4108 (angled) to Super-PC patchcord.
