SECTION IV
PERFORMANCE TESTS
4-1.
INTRODUCTION
4-2.
The procedures in this section test the electrical performance of
the model 11869A RF Plug-In Adapter. All tests can be performed without
access to the interior of the instrument.
4-3.
EQUIPMENT REQUIRED
4-4.
The equipment required for the performance tests is listed in
Table 1-2. Only the 86290A/B/C Plug-Ins will check the band changing
function.

PERFORMANCE TESTS
4-8.
Self Test
a.
This test verifies the interconnections between the 8350A Mainframe
and the 11869A Adapter. Connect the 11869A Adapter to the selected
86200 series Plug-In as described in Section II, and install this
assembly into an 8350A Sweep Oscillator.
(Selection of an 86290 RF
Plug-In is preferred so that the multiband switching circuits in the
11869A can be checked.)
b.
Switch ON the LINE power to the 8350A. Switching on the line power
or pressing the front panel INSTR PRESET button initiates a series
of self-tests within the instrument,
including one in the 11869A
that checks the interconnections between the 8350A and the Adapter.
If the 11869A Adapter is not making proper contact, the error
message E001 will be displayed on the 8350A FREQUENCY readout.
4-9•
Frequency Range
a.
When the line power is switched on or the 8350A INSTR PRESET button
is pressed, the frequency range of the installed Plug-In should be
displayed on the 8350A FREQUENCY readout. If an incorrect frequency
range is displayed, check that the Plug-In Identification Switch
A1S1 on the top panel of the 11869A is correctly coded to match the
model number of the Plug-In.
