Test Conditions
Conversion Gain (see 1)
RF Input level = -30dBmW (untuned)
Noise Figure (see 2)
Noise figure meter used. Direct reading. (DSB)
IF Output Power Level (see 3)
Measure IF output level when it is maximum level.
Conversion Gain Shift (see 4)
The conversion gain shift is defined as a change in conversion gain when supply voltage varies from Vcc = 5 V to 4.5 V or
from Vcc = 5 V to 5.5 V.
Frequency Shift (the PLL is not operating) (see 5)
The frequency shift is defined as a change in oscillator frequency when supply voltage varies from Vcc = 5 V to 4.5 V or
from Vcc = 5 V to 5.5 V.
1% Cross Modulation (see 6)

Input two signals, and increase the fud input level.
Measure the fud input level when the suppression level reaches 56.5dB.
Input two signals, measure the suppression level.
Input two signals, measure the suppression level of the IF / undesired signal.
*Undesired signal = (fp + fs) – fosc = (83.25 + 87.75) – 129 = 42 MHz.
Internal Modulation (see 7)
fd = fp : (fd input level = -30dBmW)
fud = fp ±12MHz, 100 kHz AM30%
fd = fp : (fd Input level = -35dBmW)
fud = fp ±1 MHz : (fud input level = -35dBmW)
fp = 83.25MHz : (input level = -30 dBmW)
fs = 87.75MHz : (input level = -30 dBmW)
