MLS-800 Microprocessor Controlled Ground Station Simulator:
The MLS-800 is a microprocessor controlled Ground Station Simulator designed to operate from a bench test environment. Test parameters are selected via a 44-position keyboard and displayed on test operational menus.
Test Operational Menu supports ICAO 1985 and EUROCAE ED-53A and ED-36A

RF Signal Generator Specifications:
Frequency Range: 5031 to 5090.7 MHz
Steps: 0.3 MHz
Accuracy: ±1.0 kHz (measured with Main Path in CW and Multipath OFF)
RF Output Power:
Level Range: -17 to -122 dBm
Level Accuracy: ±2.0 dB
Level Flatness: ±0.5 dB at -20 dBm (measured with 1000 Hz Fade Rate applied to Multipath with Multipath OFF, 14 dB Pad applied, and Main Path in CW, 0 dB modulation)
Note: A 0.2 to 0.4 dB variation in level at Fade Rate is normal operation and is due to residual component of Multipath signal. A 0.8 dB variation is normal for Multipath signal at Multipath = 0 dB, Main Path = OFF.
Attenuator Accuracy: ±1.0 dB
Attenuator Monotonicity: ±0.5 to 1.5 dB (each step)
Spectral Purity:
Noise Floor Offset: -105 dBc/Hz (±0.3 to 1.2 MHz from Cf)
Note 1: 105 dBc/Hz is approximately equal to -60 dBc in a 30 kHz bandwidth.
Note 2: Total spurious power should not exceed -15 dBc or -35 dBm at -20 dBm level setting from 50.0 kHz to 12.4 GHz.
Residual FM Modulation: <1 kHz peak, 0.01 to 15 kHz BW
Residual Phase Modulation: <0.5 radians peak, 0.3 to 15 kHz BW
Spurious Signal Rejection (in-band):
±0.3 to 1.2 MHz: -45 dBc
±1.2 to 30 MHz (band end): -65 dBc
Spurious Signal Rejection (out-of-band):
±5120 to 5250 MHz: -50 dBm
±50 kHz to 12.4 GHz: -35 dBm (excluding 5000 to 5250 MHz)
