GFC-8131H智慧型數(shù)字頻率計數(shù)器 的詳細介紹 規(guī)格 顯示 8 位數(shù) 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 觸發(fā)準位調(diào)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 respectivelyPeriod Range 8nS to 100S at least 7 digits displayed for per second of gate time 頻道 B 範圍 50MHz to 1.3GHz 感度 <40mVrms (10mVrms typical) 耦合 AC only 時基 Aging Rate 1 ppm, per Month 溫度 5 ppm 23°C + 5°C 電源變化 +0.005 ppm for +10% 變化 使用電源 AC 100V/120V/220V/240V ±10%, 50/60Hz 附件 操作手冊 × 1, 電源線 × 1, 測試線 GTL-110× 2 尺寸及重量 230(寬) × 95(高) × 280(長) mm, 約 2.2 公斤
