3.1 Setting Up the Transmitter
1. Place the 7410FT Transmitter in the 7180M Chassis. The operating base
plate temperature must be between -10° C to 55° C.
2. Apply AC power to the chassis. The Laser LED should be lit.
3. Using an optical power meter, measure the optical power. Insert the
meter’s cable into the Transmitter’s optical connector. Power levels should
be between 0.3 – 0.6 mW (-2 to -4 dBm).
Alternatively, use a DVM to measure the voltage at:
• pins J13-P17 through J13-P24 for the slot being measured (Refer to
Table 6 page 34 for details regarding J13 pinouts) (7180M
Rackmount)
• at pin #6 of the 9 pin connector (standalone)
The signal level should be -4.8 to -4.2 VDC.
4. On the rear panel, connect the coax cable to the RF Input Connector. The
RF LED should be lit.
5. On the rear panel, connect the fiberoptic cable to the Optical Connector.
6. The 7410FT Transmitter has AGC; no further adjustment is needed.
Note
If either LED is not lit, refer to Troubleshooting on page 36.
CAUTION
When monitoring the voltage outputs use a high resistance DVM only.
