- Recall Defaults.
- Select Vpp A
- Select DC coupling and Filter 10 kHz. Do not apply an input signal to Input A yet.
- The display should now indicate (disregard the main parameter Vpp): Vmin= 0 ± 0.015 V and Vmax= 0 ± 0.015 V
- Adjust the current limit of the DC voltage source to <200 mA.
- Connect +2.500 Vdc to Input A, using the external 50 kHz low-pass filter on the input.
- The display should now indicate: Vmin = 2.500 ± 0.040 V and Vmax = 2.500 ± 0.040 V Repeat the measurement with inverted polarity.
- Select Input A and select 10x.
CAUTION: Before the next step, make sure the input impedance is still 1 MΩ. Applying more than 12 V without proper current limiting may cause extensive damage to the main PCB, if the impedance is set to 50 Ω.
- Change the DC level to +50.00 V.
- The display should now indicate: Vmin = 50.00 ± 0.65 V and Vmax = 50.00 ± 0.65 V Repeat the measurement with inverted polarity.
- Disconnect the DC voltage from Input A. Remove the external low-pass filter.
- Select Input A and select 1x.
- Connect the LF generator to Input A, and set an amplitude of 4.000 Vpp and a frequency of 100 kHz. Verify the Amplitude with a good Voltmeter
- The display should now indicate: 4.000 ± 0.150 Vpp.
- Select Input A and select 10x.
- Change the amplitude to 18.00 Vpp.
- The display should now indicate: 18.00 ± 1 Vpp. Disconnect the LF generator from Input A.
- Select Input A and select 1x, 50 ohm, and Filter = OFF.
- Connect the RF generator to Input A and set an amplitude of 4.000 Vpp and a frequency of 100 MHz. Verify the amplitude on an oscilloscope.
- The display should now indicate: 4.000 ± 0.40 Vpp. Select Input A and select 10x.
- Change the amplitude to 18.00 Vpp.
- The display should now indicate: 18.00 ± 2.2 Vpp
- Proceed by repeating the measurements for Input B, D, and E, as described above for Input A.
