The TS9095 FM Modulation and AF Spectrum Analyser, has been designed for precision monitoring of FM Radio Broadcasts. Connected to a standard Windows PC, via a USB port, their user friendly interface displays all modulation data for onscreen analysis. Audio outputs are provided for high quality headphone or loudspeaker monitoring, with full RDS decoding available and live off-air data recording. Extensive automatic logging of broadcast data with the included ilog software. Remote control is possible with simple text file commands allowing the unit to be controlled from 3rd party software. FFT Spectrum Analyser Unique to this class of product is a 16 bit FFT Spectrum Analyser for precise FM baseband analysis. GPS The ilog software includes GPS decoding to the NMEA global standard. It will automatically scan the PC for any connected GPS NMEA compliant devices. Google Earth.kml files are generated for GPS tagged field measurement. The TS9095 units can be supplied with their own optional USB GPS receiver module. The enclosure is a solid aluminium casting, with excellent screening against external interference. This case is extremely robust for field use. This combination provides broadcast engineers, whether working on-site or as a mobile unit, with a high performance, reference class instrument. Triple bandwidth IF filters Three IF filter bandwidths are provided on the TS9095A models, providing wideband, narrowband and ultra-narrowband filters. The TS9095 has just wideband and narrowband filters. The wideband filter response, is set with a proprietary three stage, six pole Gaussian response LC filter, computer optimised and equalised for minimum overshoot and low distortion. The narrow and ultra-narrow band filters use a two stage, individually selected, 4 pole ceramic filter networks, utilising discreet low noise IF amplifier buffers. 10.7MHz IF input provides IF monitoring with the front-end shut down. 10.7MHz IF output provides IF feed through to external equipment. Antenna attenuator providing up to 30 db attenuation, with user selectable 10dB steps. Different attenuator values can be assigned to each frequency on the channel list. Balanced audio outputs for left and right channels Class AB audio amplifier for high quality audio monitoring on headphones or external loudspeakers. Additional audio stereo monitoring is available on the PC sound system. USB powered means that no other power source is required. Running from a Laptop computer, provides for mobile monitoring and logging of radio broadcasts. Windows ilog software is supplied with the unit, providing complete control and display of all measurements. This will run on a standard desktop or laptop PC. The ilog software is compatible with Windows XP, Vista, Windows 7 and Windows 8. These filters allow precise off-air measurements, offering low levels of distortion for high quality audio monitoring, via the headphone output or loudspeakers FM demodulator with distortion cancellation for linear operation. A feedback loop maintains accuracy over time and temperature by comparing deviation amplitude and phase with a DC voltage reference. All measurements of deviation, modulation power, pilot level and RDS sub-carrier are referenced to this, as are any other baseband measurements made with the spectrum analyser. FFT Spectrum Analyser 10Hz to 100kHz with 16 bit sampling, achieves a 100dB dynamic range. This can be extended to greater than 110dB with waveform averaging, allowing signals below noise to be observed and measured. Software DSP stereo decoder with excellent phase matching between channels, with lower distortion and noise than traditional analogue types. Stereo monitor with left and right channels shown on a time domain display. An additional 2D vector stereo quality display gives a visible guide to left and right channel behaviour. Stereo blend of left and right channels can be set for automatic noise control for poor signals. Multiplex record and playback with full stereo audio monitoring using PC sound system. This feature records the raw USB data from the TS9095 directly to hard disk. This can then be replayed at any time, giving a live off-air monitor. A recording can be made from any frequency on the channel list and is only limited
