Connecting Cables and a Probe

Location of the Measurement Input Terminal
Signal Input Terminal Specifications
3-8
The signal input terminal is located at the lower right section of the front panel. Connect
a cable or a probe with a BNC connector. You can select an input impedance for the
instrument's measurement input terminal of 1 MΩ or 50 Ω (see section 4.2). Therefore
you should choose a cable or probe that matches the impedance setting you entered.

* The typical value is a representative or standard value. It is not strictly guaranteed.
Do not apply a voltage that exceeds the maximum input voltage to the input
terminal. Doing so can cause damage to the input section.
Note
When connecting the probe for the first time, perform phase correction of the probe according
to the description given in section 3.6. Failure to do so will cause unstable gain across
different frequencies, thereby preventing correct measurement. Phase correction of the probe
must be performed if either the probe or the TA220 is altered.
