TECHNICAL DATA
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.
