HP8920B comprehensive tester

B is a full-featured test device, which is based on design to speed up measurement speed, improve measurement accuracy, and increase user memory (bytes, standard).
BUsing memory cards as media for data storage and wireless test procedures, B can quickly and accurately test the functionality of land mobile radios,
cellular telephones and other communication systems. Therefore, the yield and quality of products in the manufacturing process can be improved.
* Option B Cellular Adapter
* Cellular Adapter (Option B) provides a complete signal generator, modulation analyzer, data source and BR analyzer,
for (- ) and measurements on the phone. 3 replaces the cellular adapter (B option),
Used for dual-mode phone measurements, adding digital control channel test functions to fully characterize the performance of the phone, this option replaces, for mobile Test
* B option interface
For future ( ) telephone testing, test capabilities are expanded by adding interfaces to convert measurement functions to international and US frequency bands
Use an internal power meter to measure and (/pulse or continuous) signal power, maintaining the accuracy and speed of power measurement within the frequency band
Option B is a rule adaptability option, which includes 3 types of units required for standard mobile phones
The 3 and B host firmware combines the functions of these three units. In addition, the options , , and can be used for mobile testing together with the options.
* B increases throughput
* B is combined with a fast processor, adds user memory and other new features,
Its measurement speed exceeds the measurement speed of standard B interface instruments and .
* B has high performance and high accuracy as standard features
While the speed is increased, the signal level accuracy generated by B at the duplex port is
RF input/output port power measurement The accuracy is (~level). Residual FM is below.
Regarding audio testing, the standard for variable frequency notch filters is 3 ~ FM frequency deviation accuracy 3., FM distortion less than.
B, 3 and ports are all standard.
*New call processing
With the new Hohhot call processing subsystem, using B to conduct peak call testing gives people a completely new feeling.
New front panel screen simplifies manual testing as well as B programmability. In call handling mode, B emulates the cellular base,
allowing you to automatically establish and maintain the cellular link between the test device and the cellular phone. While the phone is occupying an analog voice channel or digital traffic channel, use the front panel buttons to register and initiate phone calls, paging calls, channel switching, power change and release calls, and quick parameter measurements.
*Easier programming
The new call processing subsystem also creates a more user-friendly programming interface for automated peak call testing. Advanced B commands such as paging and recording simplify code generation for phone testing.
* The programmer will also benefit from the driver.
Radio Test Software
* The RF test software family provides easy-to-use software programs for automated testing of RF transmitters and receivers.
The software family has the same set of tests included in the family, but works with B on the card.
Offering a complete range of test options for land mobile radios, cellular telephones and trunked RF communications systems. The new option software package is used for testing Fengwo mobile phones.
The standards used by mobile phones are,,, and /.
*Cellular phone and trunked radio station testing
B can test various types of analog cellular and trunked radio station systems in the world through the software package in the family.
Cellular systems include:,, dual mode, (-) and.
The cluster radio system includes R and (test included in the cluster package).
*Fast R simplifies firmware upgrades
* The B firmware is stored in the flash R and can be upgraded in minutes via the front panel, and the upgrade card can be reused.
Loading the latest version of the firmware in the shortest possible time helps maintain better process control on the production line. A single card can upgrade host B, but a set of cards is required to upgrade all numbers.
