AUTOSET SEQUENCE

Description:

If front panel settings are stored in memory locations ‘s1 to s5’ and ‘s6’ is cleared, then the range of ‘s1 to s5’ becomes a sequence of front panel settings. Such a sequence can be used as (part of) a step-by-step testing procedure. The two following methods can be used to quickly step through such a sequence. This saves time by not without having to recall each setting from a menu:

-Programming the AUTOSET key to be used as the ‘recall next setup’ key. This selection is done in the UTILITY >> AUTOSET menu.

-Using a special probe with a COMMAND switch. Two probes with COMMAND switch are delivered with each oscilloscope as standard accessory. The appropriate mode for this probe command can be selected in the UTILITY >> PROBE menu.

To return to the ‘normal’ oscilloscope mode, press the STATUS and TEXT OFF key simultaneously to recall the STANDARD SETUP.
