Performance tests
Analog AC ampl
itude accuracy (Option AC only)
This procedure is only for AWG70001A instruments with Option AC.
Required equipment Prerequisites
Digital multimeter
BNC-dual banana adapter
50 Ω BNC termination
SMA female-BNC male adapter
50 Ω SMA termination
(See page 2-21, Prerequisites.)
Measure the termination resistance. Before verifying the analog amplitude
accuracy, you need to measure the resistance of t he 50 Ω BNC t ermination.
1. Connect the BNC-dual banana adapter and 50 Ω BN
C termination to the HI
and LO inputs on the digital multimeter.
Figure 2-15: Equipment connection for measuring the termination resistance
2. Set the digital multimeter to the Ω 2wiresmode.
3. Measure the resistance and note the value as Term_R.
4. Set the digital multimeter to the DCV mode.
NOTE. Lead resistance is not included in the measurement results when using
four wire ohms. The accuracy is higher especially for small resistances. Use a
four wire method if necessary.
Check the analog AC amplitude accuracy.
1. Press the All Outputs On/Off button on the instrument to turn off all the
outputs.
2. Select the Setup tab and set the channel output mode to AC.
3. Connect an SMA-BNC adapter to the 50 Ω BNC termination on the digital
multimeter.
4. Use the 50 Ω SMA cable to connect the AC connector on the instrument to
the HI and LO inputs on the digital multimeter.
