Sideband & Carrier Feedthrough

Uncalibrated

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 +25 °C, and at each LO input power level. The +25 °C adjustment settings

were held constant during tests over 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 at each LO input power level. The +25 °C adjustment settings were held constant during tests

over temperature. The “Calibrated, over Temperature” plots represent the worst case Carrier Suppression levels

measured at T= -40 °C, +25 °C, and +85 °C.
