>>> RF SWEEP/SIGNAL GENERATOR <<<

  Shown in Figures 1 through 4 is a RF Sweep/Signal Generator Assembly using the LOA5C  and  VCO DRIVER to produce  -2.0 +/-2 dBm output at frequencies from 62.5  to 500 MHz on the front panel SMA connector.  See Figures 8 through 13 for frequency and power plots.

  For signal and swept frequency applications, the  front panel dial is used to set the center frequency (CF).  To generate a swept frequency (Delta F), connection of a triangle waveform from a function generator to the RF Sweep/Signal Generator back panel BNC connector is required.  Click on this hyperlink, GA5C Delta F, for additional Delta F information.

  Figure 3 shows three holes in the chassis bottom that allow access to three 2-pin headers.  Installation or removal of a short is required on each header to change frequency bands and produce the Stand-By (SB) mode.  The header functions are identified in Figure 6.

The GA5C is supplied with a 36 inch length  power cable permanently attached for connection to the 11K18 DC power supply.  See Figure 6 for details.  Figure 2 shows the location on the chassis back panel of the DC power connections.  +18 VDC (Green) and -18 VDC (Yellow) connect to the chassis back panel feed-thru terminals, and common ground (black) is connected to a solder lug located on the lower center of the chassis back panel.

The plots of Figures 8 and 9 were generated by setting the GA5C to Band A (J1 and J2 open).  Refer to Figure 7 for header location and note that SB is open.

The plots of Figures 10 and 11 were generated by setting the GA5C to Band B (a short installed on J1, and J2 open).  Refer to Figure 7 for header location and note that SB is open.
