SEARCH: MIN.
25 Write the absolute value of the marker 2 reading in the “Measured Value”
column of the “Performance Test Record.”
26 Repeat Step 19 through Step 25 for the other CW frequencies listed for Port 1
in the “Performance Test Record.”
In Case of
Difficulty
WARNING These servicing instructions are for use by qualified personnel only.
To avoid electrical shock, do not perform any servicing unless you are
qualified to do so.
WARNING The opening of covers or removal of parts is likely to expose
dangerous voltages. Disconnect the instrument from all voltage
sources while it is being opened.
WARNING The power cord is connected to i nternal capacitors that may remain
live for five seconds after disconnecting the plug from its power
supply.
1If the analyzer fails “Test Port 2 Magnitude Compression”:
aRepeat this test.
bReplace the A6 B sampler assembly if the analyzer still fails the test.
2If the analyzer fails “Test Port 1 Magnitude Compression”:
aRepeat this test.
bReplace the A5 A sampler assembly if the analyzer still fails the test.
16. Test Port Receiver Phase Compression
Perform this test to verify the compression/expansion phase relationships of
the analyzer’s test port receiver samplers.
