for the receiver input A. Press MEAS, INPUT PORTS, A in Step 6.
36 Repeat Step 11 through Step 16 to measure the receiver worst case 3nd
harmonic for the receiver input A.
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 source harmonics fail, replace the A3 source assembly.
2If the A receiver harmonics fail, replace the A5 sampler/mixer assembly.
3Replace the A6 sampler/mixer assembly if the B receiver harmonics fail.
17. Receiver Magnitude Frequency Response (Option 002 Only)
Perform this test to determine the receivers ability to transfer information
from RF to IF and how accurately that information is processed and displayed.
