HP 8647A和8648系列是制造大批量产品如无绳电话、寻呼机和双向无线电通信台的理想仪器。HP8647A是提供重要性能的基本型号。HP8648系列除可选用的高功率、脉冲调制和波形调制之外,在频率范围、剩余调频、电平精度和相位噪声方面都有改进。HP8648系列直到2.5GHz都具有±1dB绝对幅度精度。所有各种型号都提供了超稳定的直流调频、在低于100 MHz的频率上载频精度为±500Hz和低的射频泄漏。
The HP 8647 a and 8648 series is manufacture large quantities of products such as cordless phones, pagers, and two-way radio communication of the ideal instrument. The basic model of HP8647A is to provide the important performance. HP8648 series in addition to the optional high power modulation, pulse modulation and waveform, the frequency range, residual FM, level has improved accuracy and phase noise. HP8648 series until 2.5 GHz with + / - 1 db absolute amplitude precision. All the various models provides a super stable dc frequency modulation, in less than 100 MHz frequency carrier frequency accuracy of + 500 hz and low rf leakage. A number of applications such as receiver tuned and adjust all benefit from a simple user interface. This several signal generator is easy to learn and use, and thus no longer need experienced operators. Because of the 300 total storage register and ten sequence can be defined by the user, so the signal generator is easy to adapt to any test process. Once the Settings are stored in the register, the operator can through the front panel or remote control keyboard (HP83300A) quickly to the programming. HP83301A memory interface is also provided to register information from a HP8647/48 transfer to another. For automatic testing applications, HP8647/48 provides complete GPIB programming and using SCPI programming code. In addition, HP8648 series by providing and HP8656B with HP8657A/B signal generator is fully compatible with GPIB code and reduces the cost of software development.
