Radar detector performance verification method and apparatus

A switch-selectable frequency transmitter apparatus comprising:

• means for supplying voltage;
• a plurality of switches each operatively connected to the voltage supplying means;
• a plurality of indicators each operatively connected to a different one of the plurality of switches;
• a plurality of potentiometers each operatively connected to a different one of the plurality of indicators;
• a plurality of oscillators each operatively connected to a different one of the plurality of potentiometers, wherein each potentiometer supplies voltage to its respective oscillator;
• and
• a plurality of microstrips each operatively connected to a different one of the plurality of oscillators.

A method to verify the performance of a police band radar detector comprising the steps of:

• positioning an electromagnetic field transmitter having a plurality of oscillators adjacent but spaced apart from the radar detector;
• transmitting a desired electromagnetic signal of field strength from a transmitter to the radar detector;
• moving the position of the transmitter to a distal location from the radar detector until there is a loss of signal that inactivates an alert circuitry in the radar detector;
• utilizing the distal location as a distance standard for performance of the radar detector;
• and
• means for selectively energizing the plurality of oscillators of the transmitter to detect the desired band at the radar detector.
