3.2 Connecting a Probe
To prepare the instrument for operation, you have to connect a probe to it. The instrument is available
with the probe connectors BNC (LEMO connectors are optional).
When connecting a probe to the instrument, it’s not only important that the probe’s physical connection
be properly made. It’s also important that the instrument is properly configured to work with the installed
probe. The Instrument will operate with one or two single-element probes or with a dual-element probe.
To install a single-element probe, connect the probe cable to either of the two ports on the front of the
instrument. When two probes or a dual-element probe is connected to the instrument, the “Receive”
probe connector should be installed in the right port and the ‘Transmit’ probe connector in the left port.
