Recommended device
The connection procedure and operation when the recommended signal is
connected to the recommended instruments are described below.
• Do not apply a voltage that exceeds the maximum input voltage to the input
terminal. This may cause damage to the input section.
• Do not short or apply an external voltage to the probe compensation signal
output terminal of the DL1740, or the RF signal monitor output terminal of the
TA220. This may cause damage to the internal circuitry.
Check that the TA220 and DL1740 are turned OFF and connect them as shown in the
figure.
1. Connect a BNC cable from the RF signal monitor output terminal on the rear
panel of the TA220 to the measurement input terminal of the DL1740.
2. Connect the BNC end of the probe that is to be phase corrected to the
measurement input terminal on the front panel of the TA220.
3. Connect the other end of the probe to the probe compensation signal output
terminal of the DL1740 and the ground wire to the functional ground terminal.
