9V Battery-powered
The basic Digit Grabber dialed digit meter monitors and analyzes DTMF and dial pulse signaling through any telephone or wireless communications system. It is a high-impedence (100K ohms) instrument that bridges the line without loading. Tones are heard through the monitor speaker as they are displayed.
In the display mode, digit strings of up to 32 characters are captured and frozen on the large, alphanumeric screen. When more than 32 digits appear the first digits drop off to allow the latest characters to be shown. In the analysis mode, interdigit timing and tone burst timing are displayed for tone dialing and make/break ratio and pulses per second are displayed for pulse dialing. Digit Grabber operates on a standard 9V battery.
The basic model is a valuable test tool for technicians working with store and forward dialers; security systems; keypad maintenance on standard, mobile or cellular phones; and other CPE items using tone digits for programming or signaling.
The MF model is suited to carrier troubleshooting of MF signaling, especially for equipment used in Feature Group B or D service and does not have an analysis mode. |
