GSM/GPRS Option |
GSM/GPRS system option supporting asynchronous and synchronous measurements. The option supports the GSM 850, GSM 900, EGSM, GSM-R, GSM 1800 and GSM 1900 systems. In synchronous mode the option supports the simulation of a GSM/GPRS cell site with many optional parameters.
Signaling supported: location updating, MS/BS-originated call setup, MS/BS-originated call clearing, channel change/handover (within frequency band and interfrequency band), SMS MS/BS-originated, GPRS attach/detach, GPRS test mode (required for TX and RX testing).
Supported measurements: MS Power, Phase/Frequency error, (R)BER (class I/II), FER, Fast BER, BLER-BCS, BLER-USF, multislot measurements.

GSM/GPRS-specific Options
|
- 4480 GSM Service Test Software
The GSM Service Test Software enables the 4400 to rapidly run a suite of tests on GSM mobile phones automatically. The phone type is recognised, automatic offsets are applied for the Willtek 4916 Antenna Coupler. Comprehensive transmitter, receiver and audio checks against specifications are carried out. The phone is controlled through the serial interface. > more

- ACPM (ORFS) Option
The adjacent channel power meter (ACPM) option adds the spectrum measurement capabilities to the 4400 series. ACPM distinguishes two different measurements: spectrum due to modulation and spectrum due to switching transients.
- AM Signal Generator Option
The AM Signal Generator Option provides an AM signal generator to the 4400 series.
Output power level: -10 dBm
Modulation frequency range: 1 to 50 kHz
Modulation depth: 50 to 90%
- RAPID! Service Tests for 4400-GSM
Automatic service tests written under RAPID! the 4400 series programming language for test automation. Tests include single- and dual-band tests of GSM 850/900/1800/1900 mobile phones. Configuration allows for automatic detection of attenuation losses with the help of a golden mobile phone.
- Audio Option
The audio option adds basic audio functionality to the 4400 Series: Direct connection of microphone and loudspeaker; the built-in generator stimulates the loudspeaker or microphone of the mobile phone; frequency, voltage, distortion and SINAD measured at the same time; spectrum analyser displays audio frequency spectrum; Multitone generation via wave files.
- Basic Codec Option
The basic codec adds the full rate speech codec functionality to the audio option.
- Codec Extension Option
The codec extension adds the enhanced full rate speech codec functionality to the audio option.
- Parallel Multiple Phone Test Option
The Parallel Multiple Phone Test Option allows connection of multiple phones to a 4400. The phones are tested sequentially in order to reduce setup time. This option is ideally combined with the 4940 Bi-directional RF port (4-port).
