GPS: The raw GPS time as transmitted by the GNSS satellites (as of 15-Febru-
ary-2021, this is currently 18 seconds ahead of UTC time).
If GPS or TAI time is used, then the proper timescale offsets must be set on the
MANAGEMENT/OTHER/Time Management page. (See "The Time Management
Screen" on page166 for more information on how to configure and read the Sys-
tem Time). Local timescale allows a Local Clock to apply a time offset for Time Zone
and DST correction.
A Local Clock can be set up through the Time Management page: This
option will appear under the name of the local clock you have set up. See for
more information. Local timescale allows a Local Clock to apply a time offset
for Time Zone and DST correction.
The incoming input time information may be provided as local time, but Sys-
tem Time may be configured as UTC time, so internal computations need to
be performed. With the Timescale field set to “Local”, select the name of a
previously created Local Clock. The Time Zone and DST rules, as configured
in the Local Clock will be applied to the front panel time display. See for more
information on Local Clocks.
Baud Rate: Determines the speed at which the output port will operate.
Data Bits: Defines the number of Data Bits for the output port.
Parity: Configures the parity checking of the output port.
Stop Bits: Defines the number of Stop Bits for the output.

2.20.5 Configuring a GPIOOutput
A GPIO Output is available through the BNC and/or Multi-I/O connector on the rear panel
(see "Configurable Connectors" on page136).
Note: The fields viewable will depend on the selection for the Output Mode.
Output Mode:
Direct Output Value: Output will be low or high, determined by the Output
Value section below.
Square Wave: Output will generate a programmable square wave determined
by the configuration.
