IntraAction DFE-A4 Series Dual Frequency Source
The DFE Dual Frequency Source series are two-channel frequency generators capable of delivering up to four watts of RF power from each channel into a 50-ohm load. The DFE is used in applications where a very stable frequency difference is required.
The fixed frequency and the variable frequency channels are both synthesized from the same temperature compensated crystal oscillator (TCXO). The variable frequency is set via front panel thumbwheel switches with a setting resolution of 10 kHz. Additional variable frequency control is available with optional parallel and serial port computer interfaces.
Software is provided with the computer interface although instrument control software such as LabVIEW can be used. CW RF output is obtained by adjusting the front panel Carrier Level control. Amplitude modulation is electronically controlled with a 0 to 1 volt signal applied to the Video Input. A fixed +10 dBm RF reference output is also provided from each channel.
