Set signal generator amplitude for usable display.
b. Adjustments
(1) Connect frequency counter to 1500 MHz A8J1 (fig. 11), using cable (Hewlett-
Packard, Model 115926001, part of service kit). NOTCH FILTER FL2 assembly (fig. 11)
must be disconnected and removed for this connection.
(2) Adjust 2ND LO ADJ (fig. 11) as necessary to obtain frequency counter indication
between 1499.9 and 1500.1 MHz (R).
(3) Disconnect frequency counter and reinstall NOTCH FILTER FL2 assembly
removed in (1) above.
(4) Set BANDWIDTH switch to 100 kHz and SCAN WIDTH PER DIVISION
switch to 20 MHz.
(5) Set IF plug-in SCAN TRIGGER switch to LINE.
(6) Adjust FREQUENCY control to 0 MHz.
