2013年10月16日 · My HP-8648C (with Option 1E5) has a frequency coverage of 100kHz to 3,200MHz (with 14dBm output over the whole range), where as the newer units cover 9kHz to 3,200MHz (but with 13dBm output up to ~2,000MHz, and then 10dBm up to 3,200MHz) .

The HP 8648A/B/C/D Signal Generator is ideal for manufacturing high-volume products such as cordless telephones, pagers and two-way radios. Designed for semi-automated receiver test and a variety of general purpose applications.

Hewlett-Packard Company certifies that this product met its published specifications at the time of shipment from the factory.

Designed for semi-automated receiver test, and a variety of general purpose applications, the 8648C 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 3.2 GHz.

Combining option 1E6 with 1EA reduces maximum output power by 2 dB above 100 MHz. Below 100 MHz, maximum output is +13 dBm (typically+16 dBm for carrier frequencies between 100 kHz and 100 MHz). Accuracy is valid from maximum specified output power to –127 dBm.
