| Sound Card Oscilloscope Probe Kits | ||||
1. Introduction
 The Sound Card Oscilloscope Probe is not an ordinary oscilloscope probe. It is dedicated for PC sound Card based virtual instrument software such as Multi-Instrument. 2. Probe Specifications 1. Maximum Allowable Input Voltage: ±24 V 2. Built-in input protection circuit ensures its output to be less than 3V at all time, provided the input voltage is within the allowable range 3. Three switchable attenuation positions: 1, 2, 3, with input impedance equal to 1kΩ+sound card input impedance, 201kΩ+sound card input impedance, 10.001MΩ+sound card input impedance, respectively. Note that the sound card input impedance, either MIC IN or Line In, is card dependent and ranges from 600 Ω to 50 kΩ. 4. Frequency range: 0~200 kHz 5. Soft molded strain reliefs at all stress points assure long cable life. 6. Accessories include sprung hook, 6" ground lead. 7. Its back end is a RCA plug (male) and can be connected to an ordinary sound card through a stereo-to-2RCA converter or a mono-to-1RCA converter. No converter is required for those sound cards that have RCA jacks for input and output. 8. Can be used in Signal Generator for signal output. The output impedance is about 1 kΩ, 201 kΩ and 10.001 MΩ for attenuation switch Positions 1, 2, 3, respectively. 3. Probe kit for VIRTINS Sound Card Multi-Instrument series (1 channel, Part Number P601PC) Contains: 1 × Probe, 1 × 3.5 mm Stereo-to-2RCA converter, 1 × 3.5 mm Mono-to-1RCA converter and accessories. You may need from 1~4 sets of this probe kit per license of the software, depending on your purpose of test. We recommend the standard configuration be 2 sets per license.
