日本岩崎 SC-7217 SC-7215 SC-7207H SC-7206H SC-7205H 通用频率计数器

一、产品特点 Easy operation with one key, one action Easy-to-read fluorescent Display provides detailed information display of 5x7 dots. * Full-spelling display guide strongly supports operation Auto trigger function eliminates trigger level settings. Trigger level also can be set manually. Comparator and statistical calculation functions easily make "In-line" operations more efficient. Capable of unit conversion (rpm, speed, etc.) by using the scaling calculation function. Waveform amplitude measurement at peak voltage for input signal can be checked easily. Save/recall function of panel setup helps In-line application more efficient. Full remote control via standard equipped GP-IB (option SC-701 for SC-7205H) or RS-232 interfaces. * 200 data/sec high-speed real-time data transfer contributes to the improvement of line throughput. Option provide wide expandability Comparator output via digital I/O (SC-702). External trigger input. * 150mA, 50V output sufficient to be used in line monitoring equipment as is.

Marker signal is a signal that presupposes the brightness modulation (Z axis) of the analog oscilloscope. It is enabled at the SGL gate when the function is in between the time interval (T.INT A --> B) and phase (PHAS A --> B). Output is "Lo level" from the start of CH-A measuring to the start of CH-B measuring. Output CMOS level Reference frequency output 10MHz: Stability is the same as that for the internal reference oscillator. Marker output In the 5MHz band, L is output during actual measuring.
