Calibrated vs. Uncalibrated Test Results
During the Uncalibrated Sideband and Carrier Suppression tests, care is taken to ensure that the I/Q signal paths from
the Vector Signal Generator (VSG) to the Device Under Test (DUT) are equal. The “Uncalibrated, +25 °C” Sideband
and Carrier Suppression plots were measured at room temperature, while the “Uncalibrated, over Temperature”
Sideband and Carrier Suppression plots represent the worst case uncalibrated suppression levels measured at T=
-40 °C, +25 °C, and +85 °C.
The “Calibrated, +25 °C” Sideband Suppression data was plotted after a manual adjustment of the I/Q amplitude
balance and I/Q phase offset (skew) at +25C, and an LO input power level of + 3 dBm. This adjustment setting was
held constant during tests over LO input power level and temperature. The “Calibrated, over Temperature” plots
represent the worst case calibrated Sideband Suppression levels at T= -40 °C, +25 °C, and +85 °C.
The “Calibrated, +25 °C” Carrier Suppression data was plotted after a manual adjustment of the Ip/In & Qp/Qn DC
offsets at +25 °C, and an LO input power level of + 3 dBm. This adjustment setting was held constant during tests
over LO input power level and temperature. The “Calibrated, over Temperature” plots represent the worst case Carrier
Suppression levels measured at T= -40 °C, +25 °C, and +85 °C.
Note 1: When I leads Q, the output spectrum results in lower sideband as the desired signal.
