High Resolution 6 GHz Counter-Timer Utilizes TCXO
The TF960, a 6 GHz bench/portable frequency counter offered by Saelig, features a high quality temperature compensated internal frequency reference (TCXO) which has a low aging rate and is stable to within ±1 ppm over the full temperature range. Its short warm-up time allows accurate measurements to be made even under portable battery powered conditions. The counter-timer can measure frequency, period, pulse width, duty cycle and frequency ratio, and count/totalize events with high sensitivity between 0.001 Hz and 6000 MHz. For frequencies up to 125 MHz, the counter-timer's input is configurable as 1 MΩ or 50 Ω impedance, ac or dc coupling, and 1:1 or 5:1 attenuation. Two high frequency inputs cover a range of 80 MHz to >3 GHz and 2 GHz to >6 GHz, the latter input being via an N connector. The device operates from internal rechargeable NiMH batteries, universal ac charger/continuous ac operation and standard USB port. The TF960 frequency counter measures 10.3" x 3.5" x 9.3" mm and weighs less than 2 lbs.
