Rise Time to 90% of Level: <10ns
Programmable Period: 100ns to 1,000,000,000ns in 5ns steps, to
60,000,000µs in 1µs steps
Programmable Pulse Width: 20ns to 900ms with 5ns resolution
To configure one of the GPIO Outputs:
1. Navigate to INTERFACES > OUTPUTS: GP Output [x].
Note: I/O ports are numbered starting with 0.
The GP Output Status window will display. It provides information on the
Output Mode, if the output is Enabled, and its Current Value (i.e., low or
high output level).
2. Click the Edit button in the lower left corner. The GP Output Edit will open,
offering the following settings:
Output Mode: This is a drop-down list, offering the following options:
Direct Output Value: Output will be low or high determined by
the Output Value selection below.
1PPS: Output will occur at a rate of one pulse per second.
1PPM:Output will occur at a rate of one pulse per minute.
Square Wave: Output will generate a programmable square
wave determined by the configuration.
Custom: Output will be customized according to specific para-
meters.
Output Enabled: Check this box to enable or disable the output. If
Enabled, additional configurable parameters will be displayed.
If Direct Output mode is selected:
Signature Control: Controls when the output will be present. See
also: "Signature Control" on page69.
Output Value: Determines if the output level shall be High or Low.
Re-Initialize: Re-initializes square wave generation and aligns to 1PPS.
