GFC-8131H智慧型数字频率计数器

提供頻率與週期量測 在高頻與低頻，均具高解析度 頻率範圍：0.01Hz ~ 1.3GHz 高感度：10mVrms 1Hz 檔解析度：100nHz 可調式觸发準位控制 顯示鎖定功能

規格 顯示 8 位數 with Hz, kHz, MHz, GHz, S, mS, μS, nS and overflow Gate Time Continuously vary from 10mS to 10S, or 1 period of input depending on whichever is greater 準確度 +(Resolution +Timebase error) 頻道 A 範圍 DC 耦合 0.01Hz ~ 120MHz；AC 耦合 30Hz ~ 120MHz 感度 10mVrms typical； 50mVrms max 耦合 AC or DC, switchable 濾波器 Low pass, switchable in or out for channel A. -3dB point of nominally 100kHz 阻抗 1MΩ//40pF 衰減器 x 20dB 觸发準位調整 -2.5 VDC to +2.5 VDC 解析度 The maximum resolution for frequency measurement is 100nHz for 1Hz and 0.1Hz for 100MHz input respectively, and for period measurement is 10nS for 1Hz and 0.1fS (f=10-15) for 100MHz input respectively. At least 7,6,5 digits are display for 1S, 100mS, 10mS gate time respectively Period Range 8nS to 100S at least 7 digits displayed for per second of gate time 頻道 B 範圍 50MHz to 1.3GHz
