TEST EQUIPMENT PLANSPlease Note: Plans do not include any parts!!! PLAN 7001 - TEST SIGNAL INJECTOR A simple low cost trouble shooting aid. Used to inject a signal into various stages of radio or stereo circuitry to test signal flow. Has excellent range of signals from audio through RF. PLAN 7001 - Test Signal Injector ..................... $12.95 PLAN 7002 - LOGIC PROBE Find out what's happening in your digital logic circuitry. This digital logic probe takes only minutes to build, yet gives readings of professional quality. Long slim body makes the probe ideal for crowded circuits. Works both TTL and CMOS circuitry. Powered by circuit under test. PLAN 7002 - Logic Probe ................................
$12.95 PLAN 7003 - DIGITAL VOLTMETER PROBE This digital voltmeter probe is an ideal addition to the technician's or hobbyist's workbench. Accurately measures voltages from -9.9 through +99.9 volts DC. Professional results and professional looks in a convenient to use probe. PLAN 7003 - Digital Voltmeter Probe ............... $12.95 PLAN 7004 - FREQUENCY COUNTER This pocket sized frequency counter features automatic scaling to 250 MHz. Inexpensive IC construction. Rivals those $100.00 frequency counters advertised nationally. PLAN 7004 - Frequency Counter .................... $12.95 PLAN7005 - 100-1000 KHZ FREQUENCY STANDARD For those into building or repairing their own equipment or for the ham operator. This stable frequency standard can be used to calibrate and check equipment such as receivers, etc. PLAN 7005 - 100-1000 Khz Frequency Standard ... $12.95 PLAN 7006 - RF VOLTMETER Here is another piece of equipment you can put together yourself to save money. Invaluable for peaking your radio for highest RF or for troubleshooting. If you've ever needed an RF voltmeter to chase the mixer RF through a radio, you know what we mean. Measures RF voltages down to .5 volts. Completed unit rivals $100 to $200 commercial meters. PLAN 7006 - RF Voltmeter .............................. $12.95 PLAN 7007 - DIGITAL CAPACITANCE METER This easy to build digital capacitance meter uses common IC's and can be built for about 1/3 the cost of a commercial unit. Four test ranges allow for testing capacitors from about 10pF to 1990uF. Is a matching unit for our #7009 FREQUENCY COUNTER. PLAN 7007 - Digital Capacitance Meter ............. $12.95 PLAN 7009 - 300 MHz PORTABLE FREQUENCY COUNTER Build this precision frequency counter for less than $70.00. Includes features not available on higher priced commercial units. Built in memory displays the last frequency counter even after you stop transmitting. Frequency range from 1000 HZ to 300 MHz. No connection necessary to radio just place antenna near transmitter. Only 2 X 4 X 4 1/2. Small enough to fit on a car's dashboard or on radio itself for mobile sets. PLAN 7009 - 300Mhz Portable Frequency Counter ... $12.95 |
