The VM700T is the total solution for your baseband video and audio monitoring and measurement needs. Features such as touch sceen, an extremely fast and fully automatic measurement mode as well as full manual operation provides the first-time user, as well as the seasoned professional, an unequaled value for their test and measurement investment.
The VM700T Auto mode makes standard video transmitter measurements quickly and automatically, including those specified in RS-250C/EIA-250C, NTC-7 and RS170A. Both vertical interval and full field measurements can be made and compared with user-defined limits. A dual limit verification system is employed to generate a caution or alarm message when either limit is exceeded. Reports can be generated and printed automatically at the users scheduled times or triggered from a conditional event.
Measure mode provides virtual real-time graphic displays of measurement results automatically. Vertical interval or full field measurements including noise spectrum, group delay, K-factor, differential gain and differential phase are presented as clever, easy to understand interactive digital displays. Such displays are indispensable when extremely fast measurement update rates (up to 30 times a second) are required to provide instant feedback of critical adjustments and analysis of signal variations. User-definable limits are visually integrated into graphic display and can be used to trigger a measurement report or a user-definable macro function. A relative to reference mode allows normalizing to a signal source or eliminate signal path errors from the desired measurement. Up to two video references can be stored in NVRAM. Additionally, after downloading to a PC through the VM700T FTP driver, the video reference can be uploaded to another VM700T for reuse. A running average mode can be used to reduce the effect of noise. When additional measurement data is required, a user can custom configure measurement parameters and report format.
