About Noise generator
Create audio test tones on Windows, Mac or Pocket PC with this handy tool.NCH Sound Tone Generator lets you create audio tones, sweeps or noise waveforms using a Windows computer with a sound card or a PocketPC handheld.Tone Generator is a fine wave generator, frequency generator and signal generator that lets you create audio test tones, sweeps or noise waveforms using your computer or a PDA handheld. The full features list of this tone generator software follows but if you have any doubts about its suitability, test it as it is so simple to download and install.Typical Applications:* Generation of test tones in radio and other studios for the alignment of levels.* Calibration and testing of audio equipment or speakers.* Tuning music instruments as an accurate reference tone.* Demonstration of audio principles to students.* Acoustics testing and equalization.* Quality control and testing of sound cards.* White noise generator* Audio band signaling.* Hearing tests (under suitable medical supervision).Features* Generate sine wave, square wave, triangular waveform, saw tooth waveform, impulse, white noise and pink noise.* Supports frequencies from 1Hz to 22kHz bandwidth (subject to sound card).* Multiple simultaneous tones (1 to 16 tones can be created at the same time) (useful to create harmonics).* Mono or separate stereo operation (ideal to create dual tones or 'beats').* Tone Sweeps (Log or Linear).* Plays tone or saves as wav file.NCH Sound Tone Generator - smart and effective utility that enables you to create audio test tones

Goes high and to stop when the trigger signal goes low. 8. Real-time Noise Setup Real-time AWGN Choice: On | Off Default: Off Double-click or use the drop-down menu to enable or disable adding real-time, non-repeating additive white Gaussian noise (AWGN) to the carrier being modulated by the waveform being played. – enables the addition Real-time Noise. – disables the addition of Real-time Noise. Carrier to Noise Ratio Range: -100 to 100 dB Default: 0 dB Enter the noise power to be applied to a waveform. The carrier power is defined as the total modulated signal power before noise power is added. When you add noise, the power output from the signal generator does not change; it is the sum of carrier power and the added noise power. A positive value makes C larger than N. Carrier Bandwidth Range: 1 Hz to 200 MHz Default: 1.0 Hz Specify the bandwidth over which the noise power is integrated for calculating the carrier to noise ratio (the bandwidth of the target carrier). Also, the maximum upper range is limited to Base Sampling Rate x OSR before download is finished. Noise Bandwidth Range: 1 Hz to 200.000 MHz Default: 1.000 Hz Set or change the noise bandwidth. This parameter is available only when the RF Signal Generator connected is N5172B EXG, N5182A/B MXG. Noise Band Factor Range: 1 to 2 Default: 1 Displays the flat noise bandwidth factor for the applied real-time noise. When the Sample Clock is When the Sample Clock is > 50 MHz, noise cannot be enabled if the Noise Bandwidth Factor is 2. Any oversampling in a waveform will effectively make the noise bandwidth that many times wider than the signal bandwidth. The Noise Bandwidth is calculated as follows: The noise bandwidth is at least 0.8 * [ARB Sample Clock] * [Noise Bandwidth Factor] This parameter is available only when the RF Signal Generator connected is E4438C ESG and E8267D PSG.
