12.6 Performance Test

Trigger Voltage (Slice Level) Accuracy Test
IM 704610-01E
• Do not apply a voltage exceeding the maximum input voltage to the input
terminal of each instrument. This may cause damage to the input section.
• Do not short the output terminals of instruments or apply external voltage to it.
This may cause damage to the internal circuitry.
Items Required
The following items are required.
DC voltage generator
• Voltage accuracy: 1 mV or less
• Recommended instrument: Programmable DC voltage/current source 7651
(YOKOGAWA)
The procedure for testing the trigger voltage accuracy using the recommended
instruments is described below.
Device Connections
• Ensure that all instruments are turned OFF before making any connections.
• Connect the output terminal (OUTPUT) of the DC voltage generator to the
measurement input terminal (RF input) on the TA220.
