Installation / Operation
2.4.1
Installing and Operating the 2116-21#-1014 Downconverter (With connector option SN)
1.) Connect a -20 dBm to -0 dBm signal to RF INPUT, J1 (Figure 2.1).
2.) Connect the RF OUT, J101, to the external equipment.
3.) Connect 100- 240 ±10% VAC, 47 - 63 Hz to AC connector on the back panel.
4.) Be sure DS1 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.2).
5.) Select either INT (for internal 10MHz ref), AUTO (for internal 10MHz ref UNLESS a
external 10MHz, 0 dBm signal is connected to J2), or EXT (for external 10MHz,
0 dBm ref that is inserted at J2) on rear panel switch S1 (Figure 2.1).
6.) If EXT is selected or AUTO is selected and there is a 10MHz, 0 dBm signal at J2,
check that DS3 (yellow, EXT 10MHZ) is on (Figure 2.2).
7.) Check that a 10MHz, 0 dBm ±3 dB signal is present at the 10MHZ REF OUTPUT (J8) (Figure 2.1).
8.)
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 2.3. There is a spare fuse in the near slot.
If a fuse continues to open, the power supply is most likely defective.
