Based on the scanning method with ultra-short laser pulse, the measurement of time response characteristic was implemented on a Ultra High Speed Framing Camera (UHSFC) which has four channels. All of the four channels' curves of time response were carried out simultaneously. Actual exposure time, opening and shutting time, modulation of response and so on were revealed in these curves. The actual performance and state of the UHSFC can be examined with the help of these information. The analysis of experimental data can also be profited from the mensuration.
