Spurious responses
|
–76 dBc typical, –70 dBc max.
|
|
The main spurious response occurs at close to (2 x RF + 1.3) or (3 x RF + 2.6) MHz, where RF is the test frequency in MHz. For example, when testing a bandpass filter with a centre frequency of, say 1900 MHz, an unwanted response will occur around 632.47 or 949.35 MHz. In all known cases the levels will be as stated.
