Designed for semi-automated receiver test, and a variety of general purpose applications, the Keysight 8648D starts with the basic capabilities of the 8647A, enhances residual FM, level accuracy and phase noise performance, offers optional pulse modulation and high power, and extends the frequency to 4 GHz.
While economical, the 8648D is built to stringent quality standards, promoting reliability and measurement repeatability. In addition, the simplistic design of the front panel shortens the operator's learning curve and increases productivity. With 300 storage registers and ten user-definable sequences (accessible from a remote keypad), the 8648D easily adapts to any test procedure.
The 8648D is ideal for manufacturing high-volume products such as cordless telephones, pagers and two-way radios from 9 kHz to 4000 MHz.
