頻率計 hm8122
廠家： 德國惠美
詳細參數(shù)(pdf文件)
frequency range: 0 - 1600mhz; 3 inputs
9 measurement functions; ext. gate and arming
up to 8-digit resolution at 1second gate time
100mhz time base with 0.5ppm stability
ieee-488 bus or rs-232 interface, optional
the hm8122 is a feature-packed universal counter and, like all other instruments in the 8100 series, it is prepared for operation in automated test systems as well as for laboratory bench- top measurements. the instrument has three sensitive inputs and provides signal measurement capability from dc to 1.6 ghz.
an impressive 10ns resolution during single pulse measurement is made possible by using a 100mhz reference oscillator. resolution as fine as1ps is obtained through time interval averaging. the hm8122 displays low frequency measurements with an 8digit resolution at a 1s gate time.
besides its nine basic functions, the hm8122 offers such practical features as a prese-lectable number of pulses per rotation, offset, display-hold, single-shot measurement, external ports for gating, arming, gate-view and trigger-view. the rear panel inputs allow for measurements of channel a gated by b. an integrated calibration routine and extensive power-up self-test ensure proper and accurate operation of the counter. since any counter is only as good as its input circuitry, great care was taken in considering the technique of input signal conditioning.
the three signal inputs possess, depending upon frequency range, an input sensitivity of between 20mv and 60mv. a se-lectable low-pass filter, switchable input coupling, two 20db attenuators per channel, and the switchable trigger slope enhance trouble-free operation with nearly all input signals. automatic triggering can be turned off for complex signal measurements.
any function of the counter is programmable via the optional ieee-488 or rs-232 interface.
