From schools, factories to warehouses and distribution centers, the Netbell-NTG audio tone generator is designed to suit a wide range of applications and purposes. Using the built-in web-based scheduling software, you can easily schedule different tones or pre-recorded messages for break time alarm, no need to invest in a separate bell system. For businesses who need to make regular announcements during the day, you can plan and schedule your content, and easily change the scheduling from your web browser.
This is where the value of easy-to-use design software becomes apparent. Instead of re-starting a laborious design process, simply re-enter new specifications and try again. Return to the Design tab and increase the filter order from 3 to 4, then click Plot. Performance is improved but attenuation still varies by more than 10 dB across 160 meters.

The MTC45 is a 2-in-1 Tone and Probe generator as well as an auto ranging multimeter. The meter tests include wire trace, continuity test, clear/busy/ringing, line test and tip/ring identification. The unit is supplied with crocodile clips for non terminated cables and modular connectors for direct connections to telephone and internet wiring.
The target tuner is found in the center of the chromatic wheel. It displays the pitch and a cent meter. The tuner on this screen can be used as a stand alone feature or can be used with the other features available on the tone generator screen. When tuning with the chromatic wheel tone generator, you can use any one of the various temperaments.
All instruments in pulsed mode are automatically showing up in the appropriate section of the chronogram: generators (RF signal Generators, DC supplies) and receivers (VNA, Multimeters, Power-Meters).The measurement windows can be configured for each receiver, and once the chronogram is closed, all the settings are configured automatically in the appropriate instruments.
TSG4100A Series RF Signal Generator offer mid-range RF performance and up to 200MHz super wide modulation bandwidth at an entry-level radio frequency signal generator price. The convenient in-field software upgrade allows engineers to easily transition units from analog to more advanced vector and digital modulation capabilities, providing the most flexible configuration and best CAPEX protection.
This video shows how to set up R&SSMW200A vector signal generators and use the RF Ports Alignment option SMW-K545 together with the RFPAL PC software to generate multiple signals that are aligned in amplitude, delay and phase at the input of a multi-port DUT.
At a fraction of the cost of an audio precision analyzer, it is possible to design a very accurate sine wave generator based on the direct digital frequency synthesis (DDFS) principle, but implemented in software onto a floating-point DSP processor such as the SHARC processor. A reasonably fast floating-point DSP will meet real-time expectations and fulfill all the arithmetic and processing conditions to achieve the distortion and noise performance level set up by the most advanced SAR ADCs. Taking the benefit of the full-word data length of the SHARC core architecture either in 32-bit or 64-bit fixed-point format for the NCO phase accumulation and the proprietary, 40-bit, floating-point, extended precision to execute the sine approximation function and the digital filters used to shape the spectrum, the quantization effects (rounding and truncation noise) are drastically reduced to be considered negligible compared to the digital-to-analog converter (DAC) imperfections used for the signal reconstruction.
Building a high precision ac tone generator with similar or better distortion performance than the best analog oscillators, as in the most famous Hewlett-Packard analyzers or as described in the application note AN-1323 is not a trivial thing, even if dedicated to the audio frequency spectrum (dc to 20 kHz range). Nevertheless, as written previously, a full software implementation, performing the phase calculations (ωt) and sine function (sin(ωt)) approximations using the adequate arithmetic precision of an embedded processor can certainly help to minimize the quantization side effects, noise, and resulting spurs. This means that all the NCO functional blocks of Figure 2 are translated in lines of code (no VHDL!) to realize a software version that will meet real-time constraints to ensure the minimum sampling rate and the desired frequency bandwidth.
As mentioned earlier, the NCO suffers from spurs mainly due to the truncation of the phase accumulator output and, to a lesser extent, from the amplitude quantization done on the sinusoidal values obtained by calculation or by tabulation. The error due to phase truncation generates spurs around the carrier frequency by phase modulation (sawtooth), while sine amplitude quantization causes harmonically related spurs although were considered as random errors and noise for a long time. Today, the operation of the phase accumulator is mathematically perfectly known as described in a technical paper7 from Henry T. Nicholas and H. Samueli. After a thorough analysis, a model is presented such that the phase accumulator is considered a discrete phase sample permutation generator from which the frequency spurs can be predicted. Whatever the phase accumulator parameters (M, N, W), the length of the phase sequences equal to
Take the WRGB measurements using the software of a reference high-end spectro; JETI, Colorimetry Research, Photo Research, Minolta, Qalif, or other; and import the WRGB xyY values into ColourSpaceZRO to create a meter correction table.
A pitch generator is a type of signal generator optimized for use in audio and acoustics applications. Pitch generators typically include sine waves over the human hearing range (20 Hz to 20 kHz). Sophisticated pitch generators will also include sweep generators (a function which varies the output frequency over a range, in order to make frequency-domain measurements), multipitch generators (which output several pitches simultaneously, and are used to check for intermodulation distortion and other non-linear effects), and tone bursts (used to measure response to transients). Pitch generators are typically used in conjunction with sound level meters, when measuring the acoustics of a room or a sound reproduction system, and/or with oscilloscopes or specialized audio analyzers. 2ff7e9595c
