TECHNICAL DATA
ORBAN MODEL 8300
Pilot Protection:
–60 dB relative to 9% pilot injection, ±250 Hz (up to 2 dB composite proc-
essing drive).
Subcarrier Protection (60-100 kHz
): >= 70 dB (referenced to 100% modulation; with up to
2 dB composite limiting drive; measured with 800 line FFT analyzer using “maximum
peak hold” display).
57 kHz (RDS / RBDS) Protection:
–50 dB relative to 4% subcarrier injection, ±2.0 kHz (up
to 2 dB composite processing drive).
Connectors:
Two BNC, floating over chassis ground, EMI suppressed.
Maximum Load Capacitance:
0.047 microfarad (0
source impedance). Maximum cable
length of 100 feet / 30 meters RG–58A / U.
Filtering:
RFI filtered.
Subcarrier (SCA) Inputs
Configuration:
Subcarrier inputs sum into composite baseband outputs before digitally con-
trolled composite attenuator.
Impedance:
>600
SCA1 Sensitivity:
Variable from 220 mV p-p to >10 V p-p to produce 10% injection. Sensi-
tivity is adjustable by an internal PC-board-mounted trim pot.
SCA2 Sensitivity:
Fixed at 772 mV p-p to produce 10% injection.
Connectors:
Two BNC, unbalanced and floating over chassis ground, EMI suppressed.
19 kHz Pilot Reference:
SCA2 input can be re-jumpered to provide a 19 kHz pilot reference
output.
Remote Computer Interface
Supported Computer and Operating System:
IBM-compatible PC running Microsoft Win-
dows® 2000 (SP3 or higher) or XP.
Configuration:
TCP/IP protocol via direct cable connect, modem, or Ethernet interface.
Suitable null modem cable for direct connect is supplied. Modem and other external
equipment is not supplied.
Serial Connector:
RS–232 on DB–9 male connector, EMI-suppressed. Uses PPP to pro-
vide for direct or modem connection to the 8500 PC Remote application.
Ethernet Connector:
Female RJ45 connector for 10-100 Mbps networks using CAT5 ca-
bling. Native rate is 100 Mbps. Provides for connection to the 8500 PC Remote applica-
tion through either a network, or, using a crossover Ethernet cable, directly to a com-
puter.
Ethernet Networking Standard:
TCP/IP.
Remote Control (GPI) Interface
Configuration:
Eight (8) inputs, opto-isolated and floating.
Voltage:
6–15V AC or DC, momentary or continuous. 9VDC provided to facilitate use with
contact closure.
Connector:
DB–25 male, EMI-suppressed.
Control:
User-programmable for any eight of user presets, factory presets, bypass, test
tone, stereo or mono modes, analog input, digital input.
Filtering:
RFI filtered.
