4992A sets up corresponding qualified test ranges against many test items based on application conditions. Once the test 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 test results. 

Chinese/English operation menu, on-line test support and breakdown analysis are ailable
The default menu of 4992A is in Simplified 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 test set through the rich functions of on-line support and trouble inquiries.

Manifold interfaces, handy for control
4992A 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 ailable are LAN (local area network), Mini USB and USB Type-A. 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..

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

• Integrates double RF sources and supplies a convenient integraltest approach for evaluation of specifications covering inter-modulation of complete equipment, impedance, out-of-band suppression, etc..
  4992A owns two RF sources, 2MHz~1GHz/2.7GHz 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 setup is facile.

• The built-in standard modulation source enables FM/AM modulation.
  4992A RF source can input modulation signals from outside and an internal modulation source is also accessible, and 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.

• Effective RF signal analysisprovides assessments over transmitter signals in several aspects.
  4992A 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 ailable.

• Accurate audio analysis, simple for overall analysis on LF signals
  The complete analysis of 4992A 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.
  
  

• Multiple cable specification testing functions, quickly locate breakdowns
  The antenna feeder test of 4992A 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) helps further isolate breakdowns during radio system repair.

TYPICAL APPLICATIONS
Out-field installation, debugging and maintenance of radio equipment
Highly integrated in design, 4992A 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 transmitting/receiving equipment. As a multimeter for RF measurement, the test set 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 testequipment 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. 
4992A Radio Test Set gathers multifold meters for performance examination on various vehicle/commercial stations and wireless interphones. Test processesaresimplified, 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 behes a big advantage for mass production and routine maintenance of meters.

AM Sensitivity test of radio stations
Set up 4992 Test Set to generate RF AM signals and arrange the frequency together with receiving frequency, output frequency, modulation frequency and modulation depth of the radio station under test as per specific requirement. Choose T/R port as the RF output port. In this case, the radio station can get low power RF signals of -125dBm. Connect the audio output port of the station to the audio input port of 4992A. Enable the Audio Meter to observe SINAD of the output signals from the station. Adjust power of the RF output signals until SINAD of the audio signals under test gets close to the requirement. Following such procedure, you can easily test sensitivity of the radio station under test.
