V.3 DXDPRO-10VH APPLICATIONS AND INSTALLATION
A. APPLICATIONS
The DXDPRO modulator line was developed to process ASI or SMPTE-310M transport streams and

UHF, VHF High Band, or VHF Low Band TV Channels between 45 and 900 MHz.
b. DXDPRO-MBR - Built in receiver for Translator/Transposers with 0 dBm output on any channel
between 45 and 900 MHz.
c. DXDPRO-10U - Transmitter modulator for UHF TV with 10 W average digital power output.
Excellent for high power transmitter.
d. DXDPRO-10UR - Built in receiver for Translator/Transposer with 10 W average digital power
output on UHF TV Channels.
e. DXDPRO-10VH - Transmitter modulator for VHF High Band TV Transmitter with 10 W average
digital power output. Excellent for high power transmitters.
f. DXDPRO-10VHR - Built in receiver for Translator/Transposers with 10 W average digital power
output on all VHF High Band TV Channels.
B. TRANSMITTER INSTALATION
The modulator is enclosed in a convenient one (1) 19 inch 24 RU rack. This allows installation into most
standard racks. Do not use the front panel to hold up the modulator in the rack. RACK SUPPORT RAILS
MUST BE USED. All cable connections are located on the rear of the chassis. Several cable types are
used to make necessary connections. Please review the following list:
1. SMA 50 ohm connectors with RG 223 cable should be used for linear and non-linear connections
between the modulator and the directional couplers located before and after the mask filter. A
similar set of cables should be used to connect the forward and reflected power sample for the
Modulators power meter.
2. Type N 50 ohm connector with RG 223 or RG 8 cable can be used for the RF output.
3. DB15 cable for alarm input.
4. DB9 cable for analog and control functions.
5. AC Inlet (filtered) type.
6. Molex 3 p connector of 48 VDC auxiliary input.
7. RJ-45 Ethernet connection.
8. GPS 1pps or 10 MHz BNC 75 ohm connections.
9. ASI OR SMPTE-310M BNC 75 ohm connections.
