Acquire the Signal

Acquire the Signal

This section describes concepts of and procedures for setting up the oscilloscope to acquire the signal as you want it to.

Setting Up Analog Channels

Use front-panel buttons and knobs to set up your instrument to acquire signals using the analog channels.

1.

Connect the TPP0500/TPP1000 or VPI
probe to the input signal source.

2.

Select the input channel by pushing the
front-panel buttons.

NOTE.

If you are using a probe that does not

supply probe encoding, set the attenuation
(probe factor) on the oscilloscope vertical
menu for the channel to match the probe.

3.

Push
