5522A
Operators Manual
Perform the following sample procedure to calibrate the vertical gain.
1. Connect the calibrator to Channel 1 on the oscilloscope, making sure the oscilloscope
2. Key in the voltage level that is recommended for your oscilloscope. For example to
3. Adjust the oscilloscope as necessary. The waveform should be similar to the one
4. Change the voltage to the next value recommended for calibrating your oscilloscope
5. Repeat the procedure for each channel.
How to Calibrate the Pulse and Frequency Response on an
Oscilloscope
The pulse response is calibrated with a square-wave signal that has a fast leading edge
rise-time. Using this signal, you adjust the oscilloscope as necessary until it meets its
particular specifications for rise time and pulse aberrations.
Following pulse verification, the frequency response is checked by applying a leveled
sine wave and acquiring a frequency reading at the -3 dB point, when the amplitude drops
approximately 30 %.
9-12
is terminated at the proper impedance (1 MΩ for this example). Verify that the O
key on the 5522A is lit, indicating that the signal is connected.

Value" earlier in this chapter.
shown below, with the gain at exactly the amount specified for the calibration
settings for your oscilloscope.
This example shows the gain at 30 mV to be 6 divisions, at 5 mV per division.
model, and repeat this procedure at the new voltage level, verifying the gain is
correct according to the specifications in your manual.
