Selecting Time Record Length

The default time record length at a frequency span of 51.2 kHz is only 7.8 ms, which is usually not enough time to capture a mechanical event or observe a transducer’s time domain signal. To increase the time record length to 0.25 s, perform the following steps:

•Press the [Freq] hardkey

•Press the [RECORD LENGTH] softkey (F8)

•Enter 0.25 and then press the [S] softkey (F1)

The analyzer selects a new frequency span of 1.6 kHz, which at the default resolution of 400 lines, takes 0.25 seconds to capture. The following table outlines the time record lengths for all possible frequency spans and resolutions:

Displaying Time Waveforms

Time waveforms are displayed in a time trace. To set up the analyzer to display a single time trace of channel 1, follow these steps:

•Press the [Disp Format] hardkey.

•Press the [SINGLE] softkey (F1)

•Press the [Active Trace] hardkey.

•Press the [A] softkey (F1)

•Press the [Meas Data] hardkey.

• Press the [CHANNEL 1 2 3 4] softkey (F1) until 1 is highlighted.

•Press the [TIME CHANNEL 1] softkey (F5)

•Press the [Scale] hardkey.

•Toggle the [AUTOSCALE ON OFF] softkey (F1) until ON is highlighted.

Using Manual Arm to Capture a Single Time Waveform

Often it is desirable to observe just one time waveform in detail. To acquire just one record length at a time, follow these instructions:

•Press the [Trigger] hardkey.

•Select the [ARM SETUP] softkey (F7)

•Select the [MANUAL ARM] softkey (F2)

•Press the yellow [Start] hardkey to begin the measurement.

•Press the [Trigger] hardkey again.

Then to arm a single time record,

•Press the [ARM] softkey (F9)

One time record will be captured and displayed. To capture another time record,
