Time Domain (Zero Span)
In Time Domain, the amplitude of a single frequency is measured, rather than
sweeping a range of frequencies. The SignalHawk measures and displays the ampli-
tude 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 be measured.
1. Activate the measurement by doing one of the following:

Select Time Domain from the Spectrum Analyzer section of the Start
Menu.

Select Time Domain, in the Measurement Menu, then, in the Time
Domain submenu, press the Time Domain button (soft key 1) to turn
on the measurement.

Set the Frequency Span to 0 Hz. See “Freq & Span Menu” on page 58.
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.

Up/Down Arrows: Step increments of one second.

Right/Left Arrows: Step increments of one millisecond.

Thumbwheel: Step increments of one second per click.

Keypad: 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 “Video BW” on page 63.
