RF noise sources produce a low level level test signal for checking receiver operation and antenna testing.
Use these Noise Source Modules to test and peak receivers, test coil dip frequency, check receiver sensitivity, etc.
Wideband Noise Sources:
Part Number: NSM-50K-175M. $ 35.00 + s/h. For use in testing AM, Long Wave, Short Wave and VHF receivers: Produces broadband hiss noise from 50 KHz to 175 MHz. 50 ohms output.
Part Number: NSM-1K-1M. $ 35.00 + s/h. For use in testing audio equipment, VLF and LF receivers. Produces broadband hiss noise from 1 KHz to 1 MHz. 3 K-ohms output.
Useful for testing receivers, or as an aid in tuning up coils or antennas.
AM Band: 1 MHz
Part Number: NSMC-1 MHz. $ 45.00 + s/h. Produces narrow band hiss noise at 1 MHz. 50 ohms output.
Operates on 9 volts DC. Draws 25 uA. A 9-volt battery will last about 1 year of normal use.
Easy 4 wire connection: Green = Ground, Output = Yellow, Red = (+), Black = (-),
2 MHz 120 meter Ham Band:
Part Number: NSMC-2 MHz. $ 45.00 + s/h. Produces narrow band hiss noise at 2 MHz. 50 ohms output.
Operates on 9 volts DC. Draws 25 uA. A 9-volt battery will last about 1 year of normal use.
Easy 4 wire connection: Green = Ground, Output = Yellow, Red = (+), Black = (-),
