requirements for 8566A and older 8566B Spectrum Analyzers.
Equipment Connection
Connect the equipment as shown in Figure 3-5. on page 59 and use the following checklist
to verify the connections.
11974 LO IN to 11975A OUTPUT (SMA cable, 5061-5458)
11974 IF OUT to 8566B IF INPUT (SMA cable, 5061-5458)
11974 TUNE IN to 8566B SWEEP + TUNE OUT (BNC cable, 8120-1839; BNC ff
adapter, 1250-0080; BNC cable, 8120-2582)
11974 POWER SUPPLY to 11974-60028 PRESELECTOR POWER
8566B 1ST LO OUTPUT to 11975A INPUT (SMA cable, 5061-5458)
CAUTION When you are using an 11975A Amplifier with an 11974, you must set the
amplifier rear-panel ALC switch to ON before you connect the amplifier into
the test setup. If the ALC switch is left in the OFF position, the amplifier
output power is high enough to destroy the mixer diodes.
Set the 11975A output power to +16 dBm and verify that the amplifier's front-panel
unleveled indicator is not lit.
