AV4992A sets up corresponding qualified testing ranges against many testing items based on application conditions. Once the testing alarm function is on, the back-light color won’t change if the result fits in the range, the back-light turns to blue if the result fails the lower limit and turns to red if the result is higher than the upper limit. Users can get clear and direct views of existing testing results.

 

 

Chinese/English operation menu, on-line testing support and breakdown analysis are available

The default menu of AV4992A is in Chinese. English version can also be set. Many shortcut keys lead you to the selection menu directly, which is simple for comprehension and operation. Without special training, users can master the tester through the rich functions of on-line support and trouble inquiries.  

 

Manifold interfaces, handy for control

AV4992A Radio Test Set has a SD card slot besides RF and audio signals testing interfaces. Micro SD can extend the memory or copy internal data and documents. The interfaces available are LAN(local area network), Mini USB and USB A-type. They can enable remote control over the whole equipment, data transmission and connection to SB peripheral devices, like USB storage devices, USB mouse, USB keyboards, etc.

 

 

 

Major functions

It offers fantastic solutions for performance and specification tests on equipment including radio, interphones and so on using the highly qualified RF source. 

 

Ø  Integrates double RF sources and supplies a convenient integral testing approach for evaluation of specifications covering inter-modulation of complete equipment, impedance, out-of-band suppression, etc.

AV4992A owns two RF sources, 2MHz~1GHz and 2MHz~400MHz, to respectively control output power in the modes of single output and combined output. Complexity and cost of tests can be greatly decreased when dual-source tests are required. Meanwhile, testing set-up is facile.

 

 

Ø  Terrific spectrum purity, provides signal spur with high quality for pertaining equipment tests

The signal phase noise output by AV4992A RF source is as good as signal source of desktop equipment. -105dBc/Hz can be achieved at the phase offset of 20kHz.  

 

Ø  The built-in standard modulation source enables FM/AM modulation.

AV4992A RF source can input modulation signals from outside and an internal modulation source is also accessible. It is equipped with AM and FM required by analog communication. Certain noise output can also be added to the internal modulation signals, to simulate actual signals more vividly and detect equipment performance.

 

 

Ø  Effective RF signal analysis provides assessments over transmitter signals in several aspects.

AV4992A RF analysis can carry out evaluation on transmission performance of your equipment in every aspect, such as monitoring and examination on transmission frequency error, RF power, signal receiving intensity, spectrum characteristics, etc. RF signal measurement and analysis as well as spectrum monitoring are also available.

 

 

Ø  Accurate audio analysis, simple for overall analysis on LF signals

The complete analysis of AV4992A on audio can accurately analyze audio frequency, voltage, SINAD, THD, etc. The embedded DVM meter can measure signals containing DC component. We offer audio oscilloscope options for your direct observation and analysis on various signals under test.

 

 

Ø  Multiple cable specification testing functions, quickly locate breakdowns

The antenna feeder testing of AV4992A can examine performance of cable voltage-SW ratio, insertion loss, and return loss through measurement on SW ratio at SWR port. The ability of distance-to-fault (DTF) localization helps further isolate breakdowns during radio system repair.

 

Typical Application

 

Out-field installation, debugging and maintenance of radio equipment

Highly integrated in design, AV4992A Radio Test Set intensively combines functions of several meters with the max. size of 295mm(W)×195mm(H)×70mm(D)and the total weight even lighter than 2.6kg. The rechargeable battery with large capacity is imbedded to give you a longer working duration. It is especially suitable for out-field installation, testing and maintenance of radio transmission/receiving equipment. As a multimeter for RF measurement, the tester will surly become a necessity for radio engineers.

 

Examination on performance and mass production of radio stations/interphones

As the extensive application of radio communication, various military and civil stations and diversified communication tools , different testing equipment is required for development and mass production, for instance, signal generators, spectrum analyzers, power meters, frequency meters, oscilloscopes and audio meters. A complete radio/interphone consists of a transmitter and a receiver. Users need to switch frequently between multiple devices to accomplish tests on whole performance and specifications, which consumes manpower, resources and a great amount of time. 

 

AV4992A Radio Test Set gathers multifold meters for performance examination on various vehicle/commercial stations and wireless interphones. Testing processes are simplified, which lowers cost and improves working efficiency. The built-in “Doctor” establishes corresponding qualified ranges against certain objectives under test; the back-light of data displayed will turn to different colors based on the limits set beforehand. The ability behaves a big advantage for mass production and routine maintenance of meters.  

 

Maintenance of antenna feeders

Learning from the routine maintenance of radio stations, many breakdowns are caused by feeders and antennas rather than stations. The value of VSWR manifests the high return loss which is the result of cables, connectors or antennas. Hence, it is quite necessary to perform SWR tests on feeders and antennas so as to isolate breakdowns at feeders, connectors or antennas. AV4992A Radio Test Set implements the built-in SWR module to test SW performance of cable ports, and locate DTF using actual transmission rate of diversified cables. Our tester frees your stations from unnecessary downtime.
