MODELS 907 AND 907AF Models 907A and 907AF Signal Generators are lightweight, compact sources of rf signals. Their 7 to 12.4 GHz frequency range is continuously variable; output is displayed on a 3Vz digit LCD. Output level is continuously adjustable from +0 to -127 dBm ( + 0 to -127 dBm for the 907AF); a 3 1/2 digit LCD displays the level. Modes of operation include CW, AM, FM, PM, and sweep with internal or external modulation and trigger signals. In addition to the main RF output, an auxiliary CW output is available at a fixed level. Two sync outputs and two monitor outputs allow timing and monitoring of modulation and triggering functions. Frequency and output level control is by front panel, remote analog voltages or optional GPIB. 1.2 907A SPECIFICATIONS NOTE The following specifications apply to the Model 907A. Refer to Appendix B for 907AF specifications. 1.2.1 Versatility A cw signal source with AM, FM and pulse modulation and sweep capabilities. All parameters are independently adjustable. Pulse and FM modulation signals and sweep ramp are from an internal modulation generator or external input. Frequency and level can also be externally controlled by analog voltages or optional GPIB. Auxiliary output and internal modulator signals are available at the front panel. Modes CW: Continuous RF output. Frequency and level adjustable. FM: Internal or external signal frequency modulates the RF output. Rate and deviation adjustable. Pulse: Internal or external signal pulse modulates the RF output. Pulse width adjustable or fixed 50% duty cycle; rate adjustable. An external gate mode allows the external input to control pulse width. Sweep: Internal or external controlled sweep (to 15 Hz rate) over the entire RF frequency range.
