Setting Up A Typical

Sweep, Example

Program 3

3.Clear the controller display and run the program. ] that the REMOTE LED on the synthesizer is lit.

4.From the front panel, attempt to change the start frequency and verify that this is impossible.

5.Verify that all keys except (E) are disabled.

6.Now press the (E) key and verify that the synthesizer REMOTE LED is off and that you can modify any of the sweep functions.

7.Execute a “continue” on the controller. With the controller displaying “LOCAL LOCKOUT mode”, verify that the synthesizer REMOTE LED is again lit.

8.Attempt to change the start frequency and press (PRESET). Verify that this is impossible.

9.Now press the synthesizer (LOCAL) key and verify that still no action is taken.

10.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. Clear and reset the controller and type in the following program:
