Making Preparations for Measurements
3.6 Compensating the Probe (Phase Correction)
When making measurements using a probe on the following modules, be sure to perform
phase correction of the probe first.
• High-Speed 100 MS/s, 12-Bit Isolation Module:
720210 (HS100M12) and 720211 (HS100M12)
• High-Speed 10 MS/s, 12-Bit Isolation Module:
701250 (HS10M12) and 720250 (HS10M12)
• High-Speed High-Resolution 1 MS/s, 16-Bit Isolation Module: 701251 (HS1M16)
• High-Speed 10 MS/s, 12-Bit Non-Isolation Module:
701255 (NONISO_10M12)
• Acceleration/Voltage Module (with AAF): 701275 (ACCL/VOLT)
• Frequency Module:
701281 (FREQ) and 720281 (FREQ)
CAUTION
Do not apply external voltage to the probe compensation signal output terminal, as
it may damage the internal circuit.

ATTENTION
Ne pas appliquer de tension externe sur la borne de sortie de signal afin d’ajuster
la compensation de sonde. Cela pourrait endommager le circuit interne.
Procedure
1.
Turn ON the power switch.
2.
Connect the probe to the input terminal to which the signal is to be applied.
3.
Connect the probe’s tip to the probe compensation signal output terminal on the
front panel and connect the earth wire to the functional earth terminal.
4.
Insert a flat-blade screwdriver to the phase correction hole and turn the variable
capacitor to make the displayed waveform a correct rectangular wave.
