Specifications
Spurious Resp
onse Definitions: For each center frequency setting, any on-screen
spurious signals caused by RF input signals (blockers) mixing with local oscillators
(LO1 or LO2) at a frequency determined by the hardware settings for the IF and
LO1 frequency
.
For a given center frequency setting, use the Frequency Tuning Table to determine
the corresponding n and the IF and LO1 frequencies. (See Table 1 on page 8.) Use
the formulas
below to calculate the required input signal (blocker) frequency which
will cause a spur at the center frequency.
