2213 Operators intensity modulate the crt display. Applied signals REAR PANEL do not affect display waveshape. Signals with fast rise times and fall times provide the most abrupt intensity change, and a 5-V p-p signal will produce Refer to Figure 7 for location of item 32.
Page 7: Operating Considerations
The most reliable signal measurements are made when switch setting: the 2213 and the unit under test are connected by a com- mon reference (ground lead), in addition to the signal lead 1. Set the AC-GND-DC switch to GND before con- or probe.

2213 Operators The following general precautions should be observed when using the ADD mode. a. Do not exceed the input voltage rating of the oscillo- scope. LINE b. Do not apply signals that exceed the equivalent of about eight times the VOLTS/DIV switch settings, since large voltages may distort the display.
