NoteLO1 Frequency Tuning Time consists of the PXIe-5653 Lock Time + PXIe-5831 (LO1) Settling Time to Required Accuracy. The PXIe-5653 Lock Time is dependent on the RF Center Frequency (CF) frequency step change from initial frequency to final frequency. The relationship between the CF and the PXIe-5653 frequency is governed by the equation: F_PXIe-5653 = (FCF + FIF)/8. FIF is determined by the CF. For CF = 22.5 GHz to 31.3 GHz, FIF = 17.8 GHz; CF = >31.3 GHz to 40 GHz, FIF = 12 GHz; CF = >40 GHz to 44 GHz, FIF = 9 GHz For example, for a CF step change from 28 GHz to 39 GHz, first calculate the equivalent FPXIe-5653 for 28 GHz, which is 5.725 GHz, then the equivalent CF frequency for 39 GHz, which is 6.375 GHz. The PXIe-5653 step size is 6.375 GHz - 5.725 GHz = 650 MHz. The corresponding PXIe-5653 maximum frequency lock time is 10 ms.

LO1 x 2 refers to out-of-band leakage where an LO1 harmonic product appears at the TRX port output as a function of the configured peak power level (hence dBr units), and upconverter center frequency (UCF). The relationship between the UCF frequency and the LO1 x 2 frequency is governed by the equation: FLO1x2 =(FUCF+FIF)/2. FIF is determined by the UCF. For UCF = 22.5 GHz to 31.3 GHz, FIF = 17.8 GHz; UCF > 31.3 GHz to 40 GHz, FIF = 12 GHz; UCF >40.0 GHz to 44 GHz, FIF = 9 GHz. In the frequency range 22.5 GHz to 31.3 GHz, the minimum frequency for FLO1x2 is when CF = 22.5 GHz and here FLO1x2 = 20.15 GHz; the maximum frequency for FLO1X2 is when CF = 31.3 GHz and there FLO1x2 = 24.55 GHz. In all cases, LO1x2 is out-of-band. The in-band residual spurs are a function of the transmit tone power (hence dBc units) and are measured to within the instantaneous 1 GHz bandwidth. This does not include carrier leakage and residual image. The out-of-band spur numbers refer to spurs that are offset from the upconverter center frequency between 500 MHz to 5 GHz away, but does not include the LO1 x 2. These spurs are a function of the transmit tone power and hence have dBc units.
