Hewlett Packard HP 3561A Dynamic Signal Analyzer HP-IB Made in USA, Tested

Description: Hewlett Packard HP 3561A Dynamic Signal Analyzer HP-IB Made in USA, TestedSpectrum analysis 1/3 and 1/1 octave analysisTime capture (40 k sample)High speed ( 7.5 kHz real time rate)High accuracy ± .15 dB80 bD dynamic range, to 640 uHz resolution bandwidth Non-volatile memory option stores 127 measurements The HP 3561A is a versatile real-time spectrum analyzer for analysis of electronic, acoustic, and vibration signals up to 100 kHz. The patented design of the input provides outstanding measurement performance, ±.15 dB amplitude accuracy, 80 dB dynamic range and ± 0.003% frequency accuracy. The analyzer also has a built-in tracking generator for stimulus-response measurements. With built-in waveform math, magnitude and phase measurements are possible. Digital processing is used to provide ultra-narrow resolution bandwidths up to 640 μHz. Digital processing also speeds up measurements; a measurement with 1Hz resolution bandwidth requires only a 1.5 second sweep.In addition to spectrum measurements, the HP 3561A displays time waveforms similar to oscilloscope displays. A 40 k sample time buffer captures transients for examination in the time domain or anal- ysis in the frequency domain. The HP 3561A is also an excellent analyzer for acoustic testing. It offers 1/3 and 1/1 octave measurements and an analog A weighted filter.Spectrum AnalysisThe HP 3561A uses digital processing to achieve high performance and increase measurement speed (up to two orders of magnitude for resolution bandwidths 1 Hz or less). Results can be displayed in rms volts, volts squared, milliwatts, dBV, and dBm. Other engineering units can be displayed by entering a calibration factor and a label.In addition to standard marker features like marker to peak and peak track, the HP 3561A provides advanced marker features. Har- monic markers aid analysis and automatically compute total harmon- ic distortion (THD). Band markers automatically compute rms band level or average band power, depending on the display units selected. Sideband markers make it easy to identify the frequency spacing of modulation sidebands and automatically compute the power.Waveform RecordingThe HP 3561A is well-suited for transient capture and analysis be- cause it has a high-performance, 13-bit analog-to-digital converter with exceptional linearity. The A-to-D sampling rate is 256 kHz, and the analog anti-alias filter at the input prevents signals above 100 kHz from corrupting measurements. Lower sampling rate can be selected by changing the analysis span. To control transient capture measure- ments, the analyzer triggers on the analog level at the input, and it can be set to trigger on positive or negative slope. Trigger delays of 40 k samples pre-trigger and 1023 k samples post-trigger can be selected. The HP 3561A signal analyzer lets you capture long transients with its 40 K sample time buffer. Segments of the time buffer (1024 samples) can be expanded for easy viewing or can be transformed into spectrums so you can see the spectral content.Acoustic AnalysisCalibrated sound pressure level (SPL) measurements are possible using the Engineering Units feature of the analyzer. The sensitivity of the microphone can be measured and entered into the analyzer so the display directly reads out calibrated dBA. The built-in analog A weight filter is selectable for sound level measurements.The HP 3561A makes / and / octave measurements by digitally synthesizing the 'proportional to bandwidth' filters in custom VLSI ICs. This custom processing allows the display to update quickly and indicates any short-term changes in noise level. Both the 1/3 and 1/1 octave displays show the total sound level of the band on the right of the display. This eliminates the need for a separate sound level meter.Vibration AnalysisWhen used with an accelerometer or other motion transducer, the HP 3561A is an excellent diagnostic tool for vibration analysis. The cause of vibration problems can often be deduced by analyzing the spectral components of the vibration signal, and analysis is easy with HP 3561A harmonic, band, and sideband marker functions. The analyzer also has a built-in power source for ICP-type quartz accelerometers. Condition:Power cord not included. Photos represent the exact item that will be shipped.
