Electronic Devices, Inc. - Loran Signal Simulator LCS-300

Outputs:

Grp Trig: Provides trigger pulse at beginning of master pulse when loran C chain is transmitted.
Master: Outputs only the master pulse. Amplitude is fixed at 2V p-p at pulse maximum.
Slave1: Outputs only Slave 1, fixed amplitude of 2v p-p.
Slave2: Outputs only slave 2, fixed amplitude of 2V p-p.
Option: Output for upgrades. Not used at this time.
Composite Loran output: Connects to Loran receiver. Master, slave1, and slave2 are present at this connector, and the levels can be individually set over an 86 dB range or 50uV to 1V p-p.
Trig Out: Software selectable trigger for master, slave1, or slave2 group.

All outputs except for the Group Trig and Trig Out are 600 ohms and can tolerate DC voltages of +/-20V. The Group Trig and Trig Out output is 0-5Vwith 1K impedance. Voltage must not be applied to these outputs or damage may occur.

Controllable parameters:

The GRI, Slave time difference (TD), and master , slave1, and slave2 amplitudes can be set. ECD can be set, but applies to master and slaves equally.

GRI range: 33mS to 500mS.
GRI resolution: 100uS.
Slave1 range limits: 11000uS minimum to GRI - 11000uS maximum .
Slave2 range limits: Slave1 TD + 11000 uS minimum to GRI - 11000uS maximum.
Slave resolution: 100nS.
Master and slave amplitudes: Amplitude for master, slave1, and slave2 can be individually set from 50uV to 1V p-p in 0.3dB steps.
ECD range: +10 to -10 uS in 1 uS steps.
Serial port: Standard 9-pin serial cable. An RS232 opto-isolator option is available.
Baud rate: 9600, 8 bits, no handshake, 1 stop bit.

Internal EEPROM stores operating parameters and restores these settings when power is applied.
