The TAS 455 and TAS 465 Oscilloscopes accept signals through the front
panel input connectors labeled CH 1 and CH 2. The probes you use for
taking measurements should only be those supplied with the TAS 455 and
TAS 465 Oscilloscopes. Connecting signals to the TAS 455 and TAS 465
Oscilloscopes is also possible with the use of 50 W coaxial cables.
Before using any probe to take measurements, compensate the probe to
match the input channel. See Compensating the Probe on page 2Ć5.
The AUTOSET feature of the TAS 455 and TAS 465 Oscilloscopes automatiĆ
cally sets most of the front panel controls.
1. Connect the probe compensation signal (from the PROBE COMP
connector on the front panel) to either channel of the oscilloscope and
display that channel (see Figure 2Ć5). Turn all other channels off.
2. Press the AUTOSET button on the front panel. Wait one to three secĆ
onds to allow the instrument to adjust all the control settings.
The instrument will trigger on the waveform, display at least one complete
cycle, and center it horizontally on the CRT. The baseline of the waveform
will be at the center horizontal graticule line (see Figure 2Ć4). The intensity
level is increased if set too low for a viewable display.
