2305 Stabilock TETRA Test Set

Ensure safe and reliable communication through testing!

If a company or organization decides for a Professional Mobile Radio (PMR) system, its communication needs are usually deemed very important. Quality is important and can only be verified with measurements at frequent intervals.

• All the service measurements for TETRA base stations and radio terminals
• Wide output level range for sensitivity and blocking measurements
• Wide input level range even for high power base stations
• Low investment cost
• Serves network operators and user groups
  • public safety and security
  • transportation services
  • utilities
  • industrial companies

Aeroflex's 2305 Stabilock is a mainframe with software available for testing either TETRA radio terminals, or base stations, or both. Service personnel use the Stabilock to ensure the quality of the transmitter and receiver.



Base stations can be tested at output power levels up to 100 W. Base stations with separate connectors for transmitter and receiver can easily be connected.

Radio terminals can be tested in terms of transmit and receive parameters; the digital circuits are also tested with call setup routines in trunked mode (TMO) or direct mode (DMO).

Field service proven due to:

• low weight (< 4 kg)
• battery option
• large and high contrast screen

RF signals over joint or separate RF ports

TETRA test signals

Transmitter measurements:

• RF power
• Carrier frequency offset
• Burst power profile over time (for mobile stations)
• Timing error (for mobile stations)
• Residual carrier power
• Error vector magnitude (RMS, peak)
• Modulation spectrum
