Printing Made Easy With parallel printer port interface, screen dumps, automatic test results previously stored results sent parallel printer. These facilities available standard using serial RS-232 interface.
Live Look Listen This feature puts 2945A above peers with ability examine signals screen demodulate them simultaneously. Intermittent interference isolated quickly signals then easily identified. trace saved memory card along with time date, providing factual evidence that recalled later. This feature particularly useful when looking rogue transmissions, especially busy basestation sites. From Watts 2945A will measure power level signals such those encountered when monitoring off-air signals those found when probing circuit. Watts measurement provided without need external attenuators, high power base stations measured directly. Measurement accuracy better than guaranteed down N-Type connector, allowing radios qualified power levels. Accurate Signals signal generator provides coverage from 1.05 with output overrange) fast switching speed. Level accuracy levels above -127 dBm.

Comprehensive Oscilloscope Analysis audio signals, whether from demodulated signal audio input direct, viewed further inspection. oscilloscope either combined with measurement screen test modes `zoomed' full screen display. Different levels persistence selected allow short long term effects captured. Transient Analysis ability capture transients rising falling edge waveform provides valuable tool fault finding radios radio systems. user full control trigger level input attenuation well timebase five fixed trigger points, making this feature simple flexible operate.
Harmonic Analysis automatic harmonic analysis function included 2945A. This complements fast spectrum analyzer allows rapid check that transmitter producing large harmonics. Tones Generation Decoding tones menus include full remote control that radio workshops further automate their tasks. These other improvements response user feedback allow better control tones from level screens. POCSAG Decode built option Off-air decoding POCSAG signals provided option. This allows tone, numeric alphanumeric signals displayed. Signals with rates 4800 bits/s automatically detected making 2945A ideal surveillance tool. 2945A detect messages, user selectable (just like Pager), fixed message string.
