IOTA VTI (Video Time Inserter) Ordering Page

The IOTA-VTI v3 is a rugged, reliable, ready-to-go unit, deriving precision time from an internal GPS receiver. The ABS enclosure measures 5.2″ wide by 6″ long by 1.6″ high (130 x 150 x 40 mm). Its weight is 9.2 ounces (260 grams). It operates on 12V DC (center positive), using a 5.5 x 2.1 mm DC power connector.

It has been tested extensively, both on a bench and in the field, so we are confident it will meet your need for precision timing of video signals. If you have any questions about the product or its use, please contact us here.

IOTA-VTI v3

This is the latest version of our IOTA-sponsored video time inserter. It offers improved GPS sensitivity: more satellites will be acquired in less time. A coin cell has been added to give the GPS non-volatile memory. In addition to speeding initial satellite acquisition, the IOTA-VTI v3 will retain knowledge of leap seconds when they are added. (The most recent leap second addition was December 31, 2016.) The IOTA-VTI v3 is compatible with both NTSC (30 frames/second) and PAL (25 frames/second) video formats. Selection of format is via an internal switch that will be set to the buyer’s preference, but which can easily be changed.

External Antenna

The optional external antenna can be especially useful in an observatory or other enclosed location with poor GPS signal reception. The cord is 5 meters long (16 feet). When the external antenna is connected to the IOTA-VTI v3, the GPS will automatically disconnect from the internal antenna and connect to the external antenna.
