Entry Area
The data entry area consists of data entry keys and

each 680XXB parameter, and (2) terminating the
value entry and assigning the appropriate units
(GHz, MHz, dBm, etc.).

cated by a red LED; OUTPUT ON by a yellow LED.

The front panel has both an input connector and an
output connector.
External ALC Connector
The external ALC connector provides for leveling
the RF output signal externally using either a
detector or a power meter.

The RF output connector provides RF output from a
50
Ω

ance mismatch, the mating connector and
cable should also be rated at 50
Ω
.
