that the
REMOTE LED on the synthesizer is lit.
From the front panel, attempt to change the start frequency and
verify that this is impossible.
Verify that all keys except
(E)
are disabled.
Now press the
(E)
key and verify that the synthesizer
REMOTE LED is off and that you can modify any of the sweep
functions.
Execute a “continue” on the controller. With the controller
displaying “LOCAL LOCKOUT mode”, verify that the
synthesizer REMOTE LED is again lit.
Attempt to change the start frequency and press
(PRESET).
Verify
that this is impossible.
Now press the synthesizer
(LOCAL)
key and verify that still no
action is taken.
Execute a “continue” on the controller. With the controller
displaying “LOCAL mode”,
verify that the synthesizer REMOTE
LED is off. Also verify that all sweep functions now can be
modified via the front panel controls.
Note that the synthesizer
(LOCAL)
key produces the same result as
programming LOCAL 719 or LOCAL 7. Be careful because the
LOCAL 7 command places all instruments on the HP-IB in the local
state as opposed to just the synthesizer.

In swept operation, the synthesized sweeper is programmed for the
proper sweep frequency range, sweep time, power level, and marker
frequencies for a test measurement. This program sets up the
synthesizer for a general purpose situation. The instrument is the
same as in program 1.
