The following figure shows the instrument connections for a wideband DPD measurement.
The table shows the requirement for the instruments used in DPD measurement. For details about the options required for each instrument model, refer to System Requirements.
|Instrument Type||Instrument Model Supported|
|RF Signal Generator||
M8190A AWG (Arbitrary Waveform Generator) + E8267D PSG Vector Signal Generator 1
1. This configuration is used for wideband DPD support, in which M8190A works as IQ waveform generator and E8267D PSG works as modulator & up converter.
To set up the measurement system, follow the steps below:
Connect the PC installed with N7614B Signal Studio to the M8190A AWG, E8267D PSG, and signal analyzer through LAN.
Connect the CHANNEL 1 SAMPLE MRK OUT port of M8190A AWG to the Trigger IN 1 port on the rear panel of the signal analyzer using a BNC cable.
Connect the 10 MHz OUT port on the rear panel of the signal analyzer to the 10 MHz IN port on the rear panel of the E8267D PSG using a BNC cable.
Connect IQ baseband signal from M8190A AWG to the external IQ input port of E8267D PSG:
Connect M8190A Channel 1+ Direct OUT port to E8267D PSG Wideband I input port
Connect M8190A Channel 1- Direct OUT port to E8267D PSG Wideband I̅ input port
Connect M8190A Channel 2+ Direct OUT port to E8267D PSG Wideband Q input port
Connect M8190A Channel 2- Direct OUT port to E8267D PSG Wideband Q̅ input port
Connect the 10 MHz OUT port of E8267D PSG to the REF CLK IN port of M8190A AWG.
Connect the RF OUTPUT port of the E8267D PSG to the RF INPUT port of the signal analyzer for calibration.
