HP8920A spectrum analyzer
Frequency range: 400 KHZ ~ 1 GHZ
Product information:
8920 a radio frequency communication test device HP 8920 a is a fully functional test equipment, it can satisfy the cellular and ground maintenance and repair in the mobile communication requirements. 8920 a combination of the characteristics of 22 kinds of complete equipment, provide test cellular phone, ground mobile radio and communications systems all the functional testing, measurable to 1 GHZ. In addition, due to the adoption of new standards of electronic attenuator, improves the reliability of the model 8920 a, helps to ensure the most effective use of the test device.
Test and diagnosis of faster
The HP 8920 a by simplifying the standard measurement tasks, and provide more necessary functions in one machine and shortened the time test and diagnosis. With a single bond RX and TX and duplex test can get directly to the transmitter and receiver characteristics. All measured results as a digital or analog bar graph display on the screen. All Settings and measurement can be used on the front panel knobs easily access or change, all Settings are stored in the fixed deposit/take a register or SRAM memory card medium, in order to call in the future.
With track generator and adjacent channel power measurement of spectrum analyzer
The HP 8920 a optional synthetic spectrum analyzer can measure 400 KHZ ~ 1 GHZ signals, variable spacing is 5 KHZ ~ 1 GHZ (span). Display resolution can be in each case 1, 2, or 10 db (db) to choose between them. Adjustable frequency and amplitude or cursor automatically read relative to a benchmark in terms of relative frequency or relative amplitude. Included the tracking generator to amplitude spectrum analyzer (to 1 GHZ) and the scanning interval can be set in a way that the device characteristics of the scan. The increase of adjacent channel power measuring ability including variable bandwidth and include variable frequency offset, the performance of the typical DBC is - 70.
Signaling the encoder and decoder
Optional signal encoder and decoder supports all common signaling system, including the audio sequence, digital paging, DTMF, cluster and cellular signaling. Can choose look-up table to public standards and is easy to be modified according to different user formats. Decoder shows emitted audio or digital sequence, and instructs the tone and tone of the last time. For digital paging transmitters, decoder, coding and transmission rate, message according to address.
The HP 11807 a wireless test software
The HP 11807 a is a kind of automatic test the wireless receiver and transmitter, easy to use software packages. HP 11807 a in the HP 8920 a built-in IBASIC running on your computer, it on the ground mobile radio, cellular phones and communications systems provide full test selection. Due to its flexibility and modularity, no special programming, the user can select or change the test sequence, test parameters and through or not through the threshold. All test results are displayed on the screen, when attaching an external printer can print out the hard copy files.
The HP 11807 a variety of system support test (option 100) to give technical personnel the ability of automatic test, for usually need to perform tasks on the communication system. Support system tests include: cable fault location, intermodulation product calculation, frequency scan, field measurement and instrument Settings automatically save/call.
International cellular telephone test solution
The HP 8920 a by using HP 8920 a wireless test software to test the world's most common cellular telephone. There are three levels of testing: the telephone of artificial debugging, the function of fast examination, as well as the technical specifications of all parameters according to system testing. Supported by a honeycomb pattern include AMPS, NAMPS, TACS, NTACS, JTACS, NMT450 and NMT900. HP8920A option is to use HP11807A 004 software necessary for cellular phone test.
Cluster radio test
In view of the cluster of mobile radio test has three HP 11807 a option available. These options to support the LTR, EDACS and MPT1327 cluster radio equipment, can provide users with all kinds of automatic test.
Control by the software, the HP 8920 a can be established in cluster system of wireless radio key ability of the road test, and can retrieve into the cluster parameters of mobile radio station. Users can be displayed on all features from manual operating procedures or automatic test program of choice. If HP 8920 a has a printer can print the performance of the radio station in detail, and will highlight the fault (print with HP 8920 a option 8920). When using a HP 11807 a software test cluster system need the HP 8920 a option to 004.
