Time Domain (Zero Span)
In Time Domain, the amplitude of a single frequency is measured,
rather than sweeping a range of frequencies. The SignalHawk mea-
sures and displays the amplitude of the frequency for a specified
period (sweep time) and refreshes during the next sweep. The Time
Domain trace resembles the horizontal line display on an oscilloscope.

Note:
The center frequency will being measured.
1. Activate the measurement by doing one of the following:
z Select Time Domain in the Start Menu.
z Select Time Domain in the Measurement Menu.
z Set the Frequency Span to 0 Hz. See “Freq & Span Menu” on
page 31.
2. Press the Sweep Time soft key and enter how long a single sweep
should be using one of these methods:

Note:
Time range can be set from 1 ms to 100 s.
z Up/Down Arrows: Step increments of one second.
z Right/Left Arrows: Step increments of one millisecond.
z Mouse Scroll Wheel: Step increments of one second per click.
z Number Keys: Enter the time in seconds.

Note:
There are a limited number of pixels, so longer
sweep times mean less detail in the display.

Note:
This enables the Video Trigger in the BW & Sweep
menu. To use the Video Trigger, see “Resolution & Video BW”
on page 36.
