3.4.8 Image Rejection
Specification: 45 dB minimum
Equipment required: Signal Generator
a. Set the front panel controls as follows:
DETECTOR ...................................................AVERAGE
SAMPLE TIME Control ................................Mid-range.
FREQUENCY RANGE .................................0.009-0.035 MHz.
FREQUENCY INDICATION .......................0.220 MHz.
BANDWIDTH ...............................................200 Hz.
ATTENUATION ...........................................40 dB
b. Apply a 22 kHz CW signal at an input level of +60 dB(µV) (1 mV) to the EM-
2115 RF Input connector.
c. Peak the Signal Generator for a maximum indication on the front panel analog
meter, the digital meter should in60 dB(µV) ±2.0 dB. If not, adjust the in-
put signal level. This is the reference point for the following procedure.
d. Tune the Signal Generator to twice (2X) the IF plus the EM-2115 indicated fre-
quency.
