Sweep voltage on rear
These frequency generators are useful for sweeping ranges of up to 20x, eg. 10 kHz to 200 kHz, and display the resulting responses on an oscilloscope in X-Y mode. Set the scope to X-Y mode, and attach a coaxial cable from the sweep output on the rear of the unit to the X input on the scope. Attach the output signal of the unit as input to the device under test, and the output of the device to the Y channel of the scope. Make sure you match the impedances correctly. The frequency generator can be switched between 50 Ohm and 600 Ohm. A typical oscilloscope has a 1 MOhm input. Use a t-piece and a 50 Ohm terminator at the scope end for testing a 50 Ohm device.
The frequency generators offer DC-offset to for the signal as well, up to +/- 15 VDC at 0 dB attenuation.
These frequency generators are well used and may act slightly spuriously. At least one of the power buttons is stuck. Make sure to verify the signal on an oscilloscope before connecting to your project.
