Points to Note when Connecting a Probe
•
When connecting a probe to the instrument for the first time, perform phase correction of the
probe as described in Section 3.10 “Compensating the Probe (Phase Correction)” . Failure to
do so may result in unstable gain across different frequencies, thereby preventing correct
measurement. Make the phase correction on each channel to which the probe is to be
connected.
•
If the object to be measured is connected to the instrument directly, without using a probe,
correct measurement cannot be performed due to the input impedance.
Points to note when using a probe other than 700998 and 700929
•
Correct measured values cannot be displayed if the probe’s attenuation ratio is not “1:1”,
“10:1”, “100:1” or “1000:1”.
Setting the probe attenuation
Follow the operating procedure given in Section 5.6 “Selecting Probe Attenuation” (page 5-7)
so that the probe’s attenuation matches the one displayed below “Probe” in the soft key menu.
If they do not match, measured values cannot be read correctly.
V/div setting range(Page 5-4)
The setting range varies depending on the input module as shown below.
Input module
Setting range
High-Speed Isolation Module(701850)
5mV/div to 20V/div
High-Speed Module(701851)
5mV/div to 10V/div

Offset voltage setting range(Page 5-11)
The setting range varies depending on the input module as shown below.
For High-Speed Isolation Module
Sensitivity Range (Probe=1:1)
Offset Voltage Setting Range
5 mV/div to 50 mV/div
-0.5 V to 0.5 V
100 mV/div to 500 mV/div
-5 V to 5 V
1 V/div to 5 V/div
-50 V to 50 V
10 V/div to 20 V/div
-250 V to 250 V*
The setting resolution is 0.01 div. If the voltage scale is 5 mV/div, for example, the setting resolution will
0.05 mV.
* Do not apply an input exceeding the maximum input voltage.
For High-Speed Module
Sensitivity Range (Probe=1:1)
Offset Voltage Setting Range
5 mV/div to 50 mV/div
-0.5 V to 0.5 V
100 mV/div to 500 mV/div
-5 V to 5 V
1 V/div to 10 V/div
-50 V to 50 V
The setting resolution is 0.01 div.If the voltage scale is 5 mV/div, for example, the setting resolution will
0.05mV.
