Setting the PSG Sweep Time Requirements (PSG with Firmware ≥4.92)

By default, the PSG sweep time is automatically adjusted to the fastest possible sweep when exiting

Pass- Thru mode. To disable this feature and retain specific time selection, set the 8757D system time

to Manual.

The front panel key sequence is:

Sweep > Sweep Type > 8757D System Sweep Time to Manual

The SCPI command sequence is:

[:SOURce]:SWEep:TIME:COMP:AUTO OFF

NOTE The changes to sweep time mode are persistent. For more information on persistent memory,

refer to the User’s Guide.

The SCPI command to set up sweep time is: :SWE:TIME <val><units>.

For more on SCPI commands, refer to the SCPI Command Reference.

Setting the PSG Sweep Time Requirements (PSG with Firmware ≤4.91)

By default, the PSG sweep time is automatically adjusted to the fastest possible sweep when exiting

Pass- Thru mode. To select a different sweep time, these additional steps are required:

1. Insert line 25, that saves state 1 (SV1).

25 OUTPUT 716;”SV1”

2. Insert line 55, that sets the sweep- time of the source, :SWE:TIME <val>.

55 OUTPUT 717;”:SWE:TIME .200S”

3. Insert line 56, that saves the state into the register, sequence 0, register 1, *SAV

<reg_num>[,<seq_num>], (*SAV 1,0).

56 OUTPUT 717;”*SAV 1,0”
