EVM Jumper Configuration
13. A typical setup using Agilent's E4438C ESG vector signal generator to provide I/Q signals is as
follows:
(a) Press Preset.
(b) Press Mode → More (1 of 2) → Multitone
(c) Press Initialize Table → Number of Tones → 12 → Enter.
(d) Press Freq Spacing → 1 → MHz.
(e) Press Done.
(f) Highlight each of the first 10 rows and press Toggle State to turn OFF the first 10 frequencies and
only keep the last two rows with the BB frequency 4.5 MHz and 5.5 MHz ON.
(g) Press Multitone Off/On to ON to generate the multitone waveform.
(h) Adjust the differential I or Q voltage level by pressing Mode → I/Q → I/Q Output Control → I/Q
Output Atten → Enter 9 → Press dB.
(i) Set the common mode voltage to 0.25 V by pressing Mode → I/Q → I/Q Output Control →
Common Mode I/Q Offset → 250 → mV. Use a DC voltage meter to monitor the DC common
voltage at the inputs of I and Q and fine-tune the common mode voltage setting until it measures
250 mV.
14. Measure the TRF3722 output OIP3. The OIP3 at LO 1986.56 MHz should be around 28.5 ±2 dBm, as
shown in
