OPERATING INFORMATION
Mainframe Operation
This section presents information on how to operate the Model 6040 Universal Pulse Generator with the
Model 202H 300 V module installed. Only the details that are specific to the module are described. For
an overall description of how to use the mainframe with plug-in modules, please refer to the 6040
manual.
Front Panel Programming
When operating the instrument from the front panel, certain control keys have module dependent action,
as indicated in the 6040 manual. The aspects of these keys, and the menus they control, that are not
general to the mainframe will be listed here.
An overall chart of the menu keys, showing which menu selections are available for this module, is given
in
Table 2-4
.
{MODE}
The Mode menu for the 202H has only the Pulse Mode available. In this Mode,
flat-topped pulses of specified Width, Peak Level and Delay are produced.
{TRIG}
The Trigger source and parameter menu has four menu items: Single Cycle,
Internal Trigger (and Rate), External Trigger (and Threshold) and External Trigger
Slope.Internal Trigger Rate can be set between 0.01 H2 and 1 MHz. External
Trigger Threshold is adjustable over the 6040's entire range. The repetition rate
(from either Internal or External Trigger) should be within the allowable range for
the Width and Peak level being used (see the Timing Requirements section).
WARNING:
Do not attempt to access the polarity switch while the module is installed with the
power on. Hazardous shocks can result.
CAUTION:
Do not insert or remove the module with the mainframe power on. Damage to the
module may result.
