FUNCTIONAL FREQUENCY DESCRIPTION SYNTHESIS RF Outputs Refer to the block diagram of the RF Deck shown in 0.01 to 65 GHz Figure 2-2 (page 2-9) for the following description. The 680XXB/681XXB uses one 2 to 20 GHz YIG- tuned oscillator. All other frequencies output by the instrument are derived from the fundamental fre- quencies generated by this YIG-tuned oscillator.
Page 48: Frequency Modulation (681Xxb Only)
FUNCTIONAL FREQUENCY DESCRIPTION SYNTHESIS Frequency Frequency modulation (FM) of the YIG-tuned oscil- Modulation lator RF output by external signals is performed by (681XXB only) summing the external modulating signal into the FM control path of the YIG loop. Refer to Figures 2-1, 2-2, 2-3, and 2-4.
Page 49: Alc And Modulation
FUNCTIONAL ALC AND DESCRIPTION MODULATION ALC AND MODULATION The ALC and modulation subsystem provides automatic level control (ALC), and in the 681XXB, amplitude modulation (AM) and square wave modulation of the RF output signal. The ALC loop consists of cir- cuits located on the A10 ALC PCB, the A9 PIN Control PCB, and the A14 SDM, SQM Driver PCB.
Page 50: Amplitude Modulation (681Xxb Only)
FUNCTIONAL ALC AND DESCRIPTION MODULATION The Level Reference DAC, under the control of the CPU, provides the RF level reference voltage. By setting the output of this DAC to the appropriate voltage, the CPU adjusts the RF output power to the level selected by the user.

FUNCTIONAL ALC AND DESCRIPTION MODULATION log. After processing, the modulating signals go to the A10 PCB. On the A10 PCB, the AM Calibration DAC, under control of the CPU, adjusts the modu- lating signals for the proper amount of AM. The ad- justed modulating signal is then summed with the level reference, slope, and detector inputs into the ALC loop.
Page 54 FUNCTIONAL RF DECK DESCRIPTION ASSEMBLIES RF DECK ASSEMBLIES The primary purpose of the RF deck assembly is to generate CW and swept frequency RF signals and route these signals to the front panel RF OUTPUT connector. It is capable of generating RF signals in the frequency range of 0.01 to 65 GHz.

Page 58: Rf Signal Filtering
FUNCTIONAL RF DECK DESCRIPTION ASSEMBLIES The modulator control signal is received from the A9 PIN Control PCB where it is developed from the ALC control signal. The modulator control signal adjusts the gain of the modulator to control the power level of the RF output signals. In the 681XXB, the modulator is also used for AM and square wave modulation of the RF output signals.
