™ Windows based software package is provided for the creation, formatting and downloading of ARB waveform files to the 3410 series. A waveform library is provided on a CD containing a selection of files for testing 2G, 2.5G, 3G and 4G systems. Files can be downloaded from www.aeroflex.com/
™. Marker Control Bits Up to 3 marker bits (1-3) can be attached to each sample of IQ data. These can be used to indicate significant points in the waveform and are available as HC CMOS outputs via the rear panel Aux IN/OUT connector. Marker bit 1 can be used as RF Burst Control signal. Marker bit 2 can be used as Burst Attenuation Trigger signal to decrease (attenuate) the RF level from its nominal value. MULTICARRIER Frequency Offset Setting Range -10 MHz to +10 MHz Single Carrier Gain -60 dB to 0 dB, 0.01 dB resolution Single Carrier Start Phase -180o to+180o, 0.01o resolution Single Carrier Delay Dependant on file length, 1 ms res olution Control Mode Continuous, single or triggered operation of the ARB An external TTL trigger input signal is available on the AUX IN/OUT rear panel connector. IQ Outputs (Not applicable with Option 009 fitted) The IQ signals produced by the ARB are available on the rear panel I/AM OUT and Q/FM OUT BNC connectors. Output level is 0.5 V RMS EMF (vector sum) from a source impedance of 50 Ù. REAL TIME BASEBAND (OPTION 008) Allows the creation of digitally modulated signals using generic modulation formats. An internal data source provides PRBS or fixed patterns. External real-time data in the form of symbol data, or digital IQ data may be applied via an LVDS interface. Generic Modulation Formats PSK BPSK, QPSK, 8PSK, 16PSK 8PSK EDGE (8PSK with 3ð/8 rotation) ð/2 DBPSK, ð/4 DQPSK, ð/8 D8PSK DBPSK, DQPSK, D8PSK OQPSK (time offset) MSK GMSK FSK/GFSK 2 and 4 level symmetric QAM 16, 32, 64, 128, 256 levels For data bit to symbol mapping information refer to Technical Note "IFR 3410 Option 8 RTBB Ancillary Information" SYMBOL RATE Range 5 kHz to 2 MHz. Resolution 1 Hz BASEBAND CHANNEL FILTERS Filter Types Nyquist a = 0.1 to 0.8, resolution 0.01 Root Nyquist a = 0.1 to 0.8, resolution 0.01 Gaussian Bt 0.1 to 1.0, resolution 0.1 EDGE "Linearized Gaussian" as defined in GSM 05.04 DATA SOURCE Formats Internal Data PRBS - PN9, PN11, PN15, PN16, PN20, PN21, PN23. Fixed Pattern consisting of - 0, 0, 0, 0, 0, 0 …. 0, 1, 0, 1, 0, 1 …. 1, 0, 1, 0, 1, 0 …. 1, 1, 1, 1, 1, 1 …. User-defined symbol file stored in non-volatile memory (Max size 256 kB) External Serial Data A single bit stream representing symbol information can be applied. The bit to symbol conversion is determined from the selected modulation type. External Parallel Data Symbol information consisting of 1 to 8 data bits can be applied. External parallel and serial data is input via the LVDS connector on the rear panel. DATA ENCODING None, Differential, GSM Differential, Inverted TIMING/SYNCHRONIZATION All clock and synchronization signals are provided internally by Option 8 RTBB and made available to the user on the rear panel LVDS connector. An external clock may be phase aligned to the internal clock via a "sync" operation. External Serial Data Clock Eight times the symbol rate, for all modulation types. External Parallel Data Clock Nominal symbol rate FREQUENCY HOPPING Frequency Hop List Up to 32 frequency values. The frequency values entered represent offset values from the current RF frequency. Frequency Offset Values Offset values range ±10 MHz MODES Linear On receipt of a hop trigger, the next frequency in the list is indexed. Random On receipt of a hop trigger, an internal PRBS generator indexes through the frequency list. PN length and polynomial initial seed value are user selectable. PN values selectable from - 9, 11, 15, 16, 20, 21, and 23.
