Analog Amplitude Accuracy; Figure 2-13: Equipment Connection For Measuring The Termination Resistance - Tektronix AWG70001A Technical Reference

Performance tests

Analog amplitude accuracy

2–24
NOTE.
If checking an AWG70001A instrument with Option AC, ensure that
Channel 1 is set to Direct Mode in the Setup tab to enable the analog + and –
complimentary outputs.
Required equipment
Digital multimeter
BNC-dual banana adapter
50 Ω BNC termination
SMA female-BNC male adapter
50 Ω SMA termination
Measure the termination resistance. Before verifying the analog amplitude
accuracy, you need to measure the resistance of the 50 Ω BNC termination.
1. Connect the BNC-dual banana adapter and 50 Ω BNC termination to the HI
and LO inputs on the digital multimeter.

2. Set the digital multimeter to the Ω 2 wires mode.
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 amplitude accuracy.
1. Press the All Outputs On/Off button on the instrument to turn off all the
outputs.
2. Connect an SMA-BNC adapter to the 50 Ω BNC termination on the digital
multimeter.
