HP 8920A是功能齐全的一体式测试仪,旨在满足蜂窝和陆地移动通信市场中的服务和维修需求。HP 8920A组合了22种仪器,可提供测试蜂窝电话,陆地移动无线电和高达1 GHz的通信系统所需的全部功能。
更快地测试和排除故障
HP 8920A通过简化标准测量任务并在一个盒子中提供广泛的功能来减少测试和故障排除时间。发射器和接收器只需通过单键RX,TX和双工测试即可轻松表征。测量结果以数字测量或模拟条形图显示在单个屏幕上。使用前面板旋钮可以轻松访问和更改所有设置和测量值,并且可以将所有设置保存在非易失性保存/调用寄存器或SRAM卡介质中,以备将来使用。
具有跟踪发生器和相邻信道功率的频谱分析仪
HP 8920A的可选合成频谱分析仪可测量范围从5 kHz到1 GHz(全范围)的400 kHz到1 GHz的信号。显示分辨率可以从1、2或10 dB每格中选择。可调标记可自动从参考值中读出频率和幅度,或相对频率或幅度。频谱分析仪随附的跟踪发生器可以对振幅和扫描范围完全可设置(至1 GHz)的设备进行扫频表征。新增加的相邻信道功率测量功能包括可变带宽和可变频率偏移。典型性能为-70 dBc。
信令编码器和解码器
可选的信令编码器和解码器支持所有常见的信令格式,包括音序,数字寻呼,DTMF,中继和蜂窝信令。通用标准是列表可选的,并且可以轻松地针对不同的用户格式进行修改。解码器显示发送的音频或数字序列,以及音频或音频对的持续时间。对于数字寻呼发射机,解码器将显示地址/代码,消息和传输速率
HP 8920A is a full-feature, one-box test set designed to meet service and repair needs in the cellular and land mobile communications market. Combining 22 instruments, the HP 8920A offers full functionality needed in testing cellular phones, land mobile radios, and communications systems up to 1 GHz.
Test and Troubleshoot Faster
The HP 8920A decreases test and troubleshooting time by simplifying standard measurement tasks and providing extensive capability in one box. Transmitters and receivers are simply characterized with single-key RX, TX, and duplex tests. Measured results are displayed on a single screen as either digital measurements or analog bar graphs. All settings and measurements are easily accessed and changed using the front-panel knob, and all settings can be saved in nonvolatile save/recall registers or on a SRAM card media for future access.
Spectrum Analyzer with Tracking Generator and Adjacent Channel Power
The HP 8920A's optional synthesized spectrum analyzer measures signals from 400 kHz to 1 GHz with variable spans from 5 kHz to 1 GHz (full span). Display resolution is selectable from 1, 2, or 10 dB per division. The tunable marker provides automatic readout of frequency and amplitude, or of relative frequency or amplitude from a reference. The tracking generator included with the spectrum analyzer allows for swept characterization of devices with fully settable amplitude and sweep spans (to 1 GHz). The newly added adjacent channel power measurement capability includes both variable bandwidths and variable frequency offsets. Typical performance is -70 dBc.
Signaling Encoder and Decoder
The optional signaling encoder and decoder support all common signaling formats, including tone sequential, digital paging, DTMF, trunking, and cellular signaling. Common standards are list-selectable and easily modified for different user formats. The decoder displays the tone or digital sequence transmitted, and the duration of the tone or tone pair. For digital paging transmitters, the decoder will display the address/code, the message, and the transmission rate.
