If your generator cannot output 6 divisions of amplitude, set it to its maximum output. The –3 db limit can be calculated as:
0.707 reference amplitude.
e. Display the test signal: Do the following subparts to first display the
reference signal and then the test signal.
H Press MEASURE; then press the main-menu button Select
Measrmnt for CHx.
H Press the side-menu button more, if needed, until the menu label
Frequency appears in the side menu (its icon is shown at the left).
Press the side-menu button Frequency.
H 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.
H Press CLEAR MENU.
H Set the generator output so the CHx Pk-Pk readout equals the
reference amplitude in Table 1–4 that corresponds to the vertical
scale set in substep d.
H Press the front-panel button SET LEVEL TO 50% as necessary to
trigger a stable display. At full bandwidth, you may also want to
make small, manual adjustments to the trigger level. You can use the
TRIGGER LEVEL knob to do this. (Full bandwidth varies with
TDS model as is shown in Table 1–4).
