10 / 12 page ![]() Frequency response ±0.5 dB at 200 Hz to 5 kHz ±2 dB at 100 Hz to 20 kHz Level Accuracy ±2% at 1 kHz ± accuracy of 2945A, 2946A or 2948 Output Level 1 mV to 2.5 V RMS across 600 Ω ANALOG SYSTEMS CARD (OPTION 2) This option provides automatic testing for cellular,trunked and FM radios and a BASIC Interpreter for customized tests. PARALLEL INTERFACE (OPTION 4) Allows direct connection of a parallel printer. Additionally provides 4 software programmable output lines. Printer Port Connector 25 way female D type Printers Supported 75, 100, 150 dots per inch laser printers, FX 80, FX 100 Epson for- mat. Accessory Port Connector 9 way female D type Outputs 4 independently programmable output lines, each one configurable as a logic line or as a relay contact closure. +5V supply available. GPIB (OPTION 5) Capability For printing, remote instrument control or for programming of user defined test sequences. Complies with the following subsets defined by IEEE488:- SH1, AH1, T6, L4, SR1, RL1, DT0, EI, DC1 MEMORY CARD DRIVE AND REAL TIME CLOCK (OPTION 6) The memory card facility allows the storage of results, set-ups screen dumps and user programs with SRAM cards. Meets PCMCIA 2 stan- dard. Allows the current date and time to be stored with results to the mem- ory card and/or printed with a screen dump. SSB DEMODULATOR (OPTION 8) The SSB demodulator allows signals to be demodulated either via the internal loudspeaker or via the accessory socket. Provides demodula- tion of SSB signals (upper and lower sideband) Frequency Range 400 kHz to 1 GHz AF Demodulation Range 10 Hz to 15 kHz Distortion Typically less than 3% at 1 kHz (300 to 3.4 kHz) Detection Range 2 µV to 150 W Features Automatic detection of USB or LSB. BFO can be used for tuning of carrier for AM and FM radio’s. OCCUPIED BANDWIDTH MEASUREMENT (OPTION 9) Calculates the bandwidth of a signal displayed on the spectrum analyz- er. Frequency Range 1 MHz to 1 GHz Display Resolution 3 digits Accuracy 20% Bandwidth Measurement Range 3 kHz minimum Ratio range 90% - 99% selectable in 0.1% steps NMT CELLULAR SOFTWARE (OPTION 10) NMT 450 NMT 900 Benelux NMTF Austria Spain Malaysia Indonesia Saudi 1 Saudi 2 Thailand Oman Tunisia Hungary Poland Russia Czech Bulgaria Slovenia Turkey USER DEFINED NMT AMPS CELLULAR SOFTWARE (OPTION 11) E-AMPS N-AMPS USER DEFINED AMPS TACS CELLULAR SOFTWARE (OPTION 12) E-TACS TACS 2 C-TACS I C-TACS II J-TACS N-TACS USER DEFINED TACS MPT 1327 TRUNKING SOFTWARE (OPTION 13) BAND III JRC UK WATER HONG KONG AUTONET AMT MADEIRA NL-TRAXIS NZ MPT1327 PH-INDO USER DEFINED MPT PMRTEST SOFTWARE (OPTION 14) USER DEFINED PMR for FM radio’s EDACS ™ ™ RADIO TEST SOFTWARE (OPTION 15) Provides Auto/Manual test capability for EDACS ™ radios.
