When set to Positive, the output will initially be at 0 Volts. When active, will go high for the specified pulse width time, after which it will return to 0. The voltage level while high will de- pend upon the load and the setting of the output voltage adjustment on the back panel.
If set to Negative, the output will normally be at the high voltage level. When the output is activated, it will go to 0 Volts for the specified pulse width time, after which it will return to the high level again.
T2 Menus
Channel 2 (T2) has some special features designed to be particularly useful when used as a
T2:Enable
This menu is used to separately enable or disable the output of Channel 2, independent of the other channels. If set to On, Channel 2's output will be active under the same conditions as the other channels. When set to Off, Channel 2's output will remain disabled under all condi- tions.
T2:Gate
When not in External Trigger mode, the Ext/Gate input can be used to gate the output of all output channels or just the output of Channel 2. In order to use the input to gate Channel 2, the GATE selection in the Main Menu set must be set to Off and the T2:Gate selection must be set to Low or High.
The setting of the T2:Gate menu is used to determine when the signal is active. If the gate menu is set (active) High, Channel 2 pulses will only be generated if the Ext/Gate input signal is greater than 3.5 Volts. If set to (active) Low, outputs will be enabled as long as the Ext/Gate input signal is less than 2.0 Volts.
