Section 6 : Measuring a Single Channel Time Waveform

This section contains procedures for setting up and measuring a single channel time waveform using an AGILENT 35670A Dynamic Signal Analyzer. Included are steps to select single channel operation, set up the trace time length, and set up triggering to capture a transient event. Instructions will also be presented to scale the time trace.

Selecting Single Channel Operation

To measure a single-channel time waveform, turn on the AGILENT 35670A and then:

•Press the [Inst Mode] hardkey

•Press [CHANNELS 1 2 4 ] softkey (F7) until 1 is highlighted.

Note: if the AGILENT 35670A was already turned on and in an unknown state, then preset the analyzer by doing the following:

•Press the green [Preset] hardkey

•Press [DO PRESET] softkey (F1).

Then set the instrument mode to single channel as above.
