Square Wave: Output will generate a programmable square wave
determined by the configuration.
Output Enabled: Check this box to enable or disable the output. If Enabled,
additional configurable parameters will be displayed.
Output Value: Determines the output level (Low or High).
Signature Control: Controls when the output will be present. See also: "Sig-
nature Control" on page183.
Edge: Used to determine if the on-time point of the output is the Rising or
Falling edge of the signal.
Offset: Accounts for cable delays and other latencies [nanoseconds].
Period: Sets the period of the square wave (in ns or μs scale).
The wave’s frequency will display at the top of the window once you
have configured the output. The frequency is calculated based on the
Period and Period Correction settings.
Period Correction: Period correction allows for the generation of more pre-
cise frequencies at the expense of additional period jitter. Over a length of
time, the true square wave period comes to:
Period + [(numerator/denominator) * 5 ns]
Pulse Width: Pulse width of the output [nanoseconds].
On-Time Point Pulse Width: The on-time point pulse width is the pulse
width of the first square wave pulse aligned to the 1PPS On-Time Point.
This is only active when the alignment count is non-zero [nanoseconds].
Alignment Count (s): The alignment counter determines how often (in
seconds) the square wave will be aligned back to the 1PPS. Setting zero will
disable PPS alignment beyond the initial alignment.
Time Alignment: (Enabled/Disabled) The time alignment enable changes
the function of the alignment counter to align the square wave whenever
the current time’s seconds value is a multiple of the alignment count. For
example: If time alignment is enabled and alignment count is set to 15
seconds, the square wave will be aligned to the 1PPS when the seconds
value on the time display equals 00, 15, 30, 45.
Re-Initialize: Re-initializes square wave generation and aligns to 1PPS.
2.20.6 Configuring a HaveQuick Output
A HaveQuick Output is available by default configuration through the Multi-I/O
connector and can be optionally configured through the BNC connector on the
rear panel (see "Configurable Connectors" on page157).
To configure the settings of a HAVE QUICK Output, go to its Edit window.
