Chapter 3: Test Equipment and Spares 9 CHAPTER 3: TEST EQUIPMENT AND SPARES RECOMMENDED TEST EQUIPMENT Daniels Electronics recommends the following test equipment for maintenance of an MT-4E radio system: +13.8 Vdc Power Supply Daniels PSA-12-40-RB-00 (rated for current draw of equipment) (40 Amp rack-mounted power supply) ICT ICT24012 (60 Amp desktop power supply) ICT ICT12012 (10 Amp desktop power supply) Current Meter / Multimeter Fluke 75 Multimeter Communications Service Monitor Marconi Instruments 2965A (Analog) Aerofl ex IFR 1200 (Super S) Aerofl ex IFR COM-120 Communications Service Monitor Aerofl ex IFR 2975 (P25 Digital and Analog) Aerofl ex IFR 3920 General Dynamics R2670 Alignment Tools RF Signal Sampler Wattmeter Daniels A-TK-04 Bird Model 4275 Variable RF Signal Sampler Bird Model 43 Wattmeter It is recommended that when in the shop / service area, the Communications Service Monitor be frequency locked to an external reference (WWVH, GPS, Loran C) so that the high stability local oscillator may be accurately set to within its ±1 ppm frequency tolerance. The test equipment should be calibrated on an annual basis to ensure accurate measurements. MG-001 Daniels MT-4E Radio Systems www.danelec.com Maintenance Guide
