>>> MGA2K Delta F Function <<<

  Shown in Figure 1 is an oscilloscope display of the signal level at the MGA2K VCO tuning terminal (V-T) with DC only , no AC component.  Refer to the right side of Figure 1 for the following information.  Cursor 1 is on the base line and Cursor 2 is on the trace which produces a Delta V of 8.00 VDC.

  Figure 2 is a spectrum analyzer display of the MGA2K output.  The marker (MKR) is on the peak of the trace (1.5013 GHz, -13.41 dBm).  To keep the spectrum analyzer from being over driven, a 20 dB attenuator is required between the MGA2K output and spectrum analyzer input.  The MGA2K power output level is 20 - 13.41 = 6.59 dBm.

  Figure 3 is the oscilloscope display of the signal level at the internal VCO tuning terminal (V-T) with 8 VDC and 2.6 Volt P-P AC.  Refer to the right side of Figure 3 for the following information.  Cursor 1 is on the waveform valley and Cursor 2 is on the waveform peak which produces a Delta V of 2.6V P-P.  This VCO drive level at the V-T terminal produces the MGA2K output displayed by the spectrum analyzer screen image of Figure 4.  Refer to the bottom of spectrum analyzer display of Figure 4 for the following information. Span = 500 MHz or 50 MHz / divison.  Delta F is approximately 200 MHz.
