1599-10 NOISE SOURCE
SECTION 1 GENERAL
1.1 Equipment Description- The Model 1599-10 Noise Source provides 70 MHz band limited noise in 0.1dB
increments and summing of an external signal. Broad band noise goes to precision attenuators controlled by front
panel “up” and “down” pushbutton switches via the microprocessor controller. The front panel display shows
C/No or attenuation of the noise from a 50 dB- Hz C/No level calibrated for a -20 dBm carrier level. Bandpass
filters are selected with on board jumpers to band limit the noise at 70 MHz. The 1599-10 has a front panel red
LED that lights if the ambient temperature is outside the +20 to +40 C calibrated temperature range. A yellow LED
on the front panel indicates if in remote operation.
