Performance Tests

Performance Verification Procedures

Display the test signal:

Do the following subparts to first display the

reference signal and then the test signal.

Press MEASURE; then press the main-menu button Select

Measrmnt for

CHx

Now press the side menu button more until the menu label Pk-Pk

appears in the side menu (its icon is shown at the left). Press the

side-menu button Pk-Pk.

Press CLEAR MENU.

Set the generator output so the CHx Pk-Pk readout equals the

reference amplitude in Table 1-5 that corresponds to the vertical

scale set in substep d.

Press the front-panel button SET LEVEL TO 50% as necessary

to trigger a stable display.

Measure the test signal:

Increase the frequency of the generator output to the test fre-

quency in Table 1-5 that corresponds to the vertical scale set in

substep d.

Set the horizontal SCALE to 1 ns. Press SET LEVEL TO 50% as

necessary.

Read the results at the CHx Pk-Pk readout, which will automati-

cally measure the amplitude of the test signal. See Figure 1-9.

Second, read the results

from the readout of

measurement Pk-Pk.

First, increase the reference

frequency to the test

frequency; then decrease the

horizontal scale.
