2.4 Operation
2.4.1 Installing and Operating the 1200-07
1. Install the 1200-07 in the equipment rack.
2. Connect 100-240 ±10% VAC, 47 - 63 Hz to AC IN on the back panel (Figure 2.2).
3. Be sure the POWER LED, DS6, is on (Figure 2.3).
4. Connect a 50-200 MHz signal to IF INPUT, J109 (Figure 2.2).
5. Select Manual Gain Control (MGC) or Automatic Gain Control using switch, S5 (Figure 2.2).
6. Connect IF OUT 1 and IF OUT 2 (Figure 2.2) to the desired equipment, and check for proper level
using IF MONITOR on the front panel (Figure 2.3).
7. If in MGC mode adjust rear panel potentiometer R123 for the desired gain (Figure 2.2).
8. Adjust output to desired level using front panel attenuator pot, R3 (Figure 2.3). Clockwise rotation
provides increased output level (full clockwise = 0 dB atten, full counter-clockwise = 30 dB atten).
9. AC Fuse - The fuse is a 5 mm X 20 mm, 2 amp slow blow (Type T) and is inserted in the far slot in
the drawer below the AC input as shown in Figure 2.4. There is a spare fuse in the near slot. If a
fuse continues to open, the power supply is most likely defective.
