CH2 input impedance . ......... 1MW
Horizontal
Sweep . .................... 20ms/div
Trigger
Source . .................... CH1
Coupling .................... DC
Slope ...................... Positive
Level ...................... 100mV
Mode . ..................... NORMAL
2. Set the function generator (AFG310) controls as follows:
Function ........................ Square
Mode .......................... Continuous
Parameters ......................
Frequency .................. 10.1 kHz
Amplitude . .................. 2.0Vinto 50 W (4.0 V into 1 MW)
Offset . ..................... 1.0Vinto 50 W (2.0 V into 1 MW)
Output . ........................ Off
3. Follow the substeps below to set the AWG710 Arbitrary Waveform
Generator controls and to select the waveform file:
a. Push UTILITY (front-panel)!System (bottom)!Factory Reset
(side)!OK (side).
b. Push SETUP (front-panel)!Run Mode (bottom)!Gated (side).
c. Load the MODE.WFM file.
Refer to Loading Files on page 4–10 for file loading procedures.
d. Push HORIZONTAL MENU (front-panel)! Clock (side).
Check Gated Mode
