Two connector pins are located on the front panel. The right pin is on ground level. The
left pin supplies a square wave signal for the adjustment. You can choose between two
frequencies for usual low frequency compensation and additional high frequency com-
pensation. The rise time does not differ between the settings.
1. Connect the BNC connector of the probe to input CH1.
2. Connect the probe's ground connector to the right compensation pin, and the tip
with the left pin.
3. Select SETUP > "Probe Adjust".
4. Select the frequency for the adjustment signal by pressing the corresponding soft-
key. The following frequencies are available:
●
1kHz
: A square wave with a frequency of f = 1 kHz is generated at the probe
compensation pin. Use this setting to adjust the LF band of the probe.
●
1MHz
: A square wave with a frequency of f = 1 MHz is generated at the probe
compensation pin. Use this setting to adjust the HF band of the probe.
●
Automatic
: A square wave is generated at the probe compensation pin. The
frequency of the square wave depends on the defined time base. If the time
base becomes too small to display the 1 kHz wave, it is automatically switched
to a 1 MHz wave. It is recommended that you do not use this setting for probe
compensation.
5. Press AUTOSET.
A square wave appears on the display.
6. Adjust the compensation trimmer of the probe to optimum square wave response.
For details, refer to the documentation of your probe.
