Features:
- Easy operation with one key, one action
- Easy-to-read fluorescent indicator tube provides detailed
information display of 5x7 dots.
* Full-spelling display guide strongly supports operation
- Auto trigger function eliminates trigger level settings. Trigger
level can also be set manually.
- Comparator and statistical calculation functions easily make
line inspection operations more efficient.
- Capable of unit conversion (revolution, speed, etc.) by using
the scaling calculation function.
- Waveform amplitude at peak voltage measuring for input signal
can be checked easily.
- Save/recall function of panel setup helps make inspection
routines more efficient.
- Full remote control via standard equipped GP-IB (option SC-701
for SC-7205) or RS-232C interfaces.
* 200 data/sec high-speed real-time transfer contributes to
the improvement of line throughput.
- Options 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.
-High-accuracy measuring using high stability reference oscillators
(SC-703/SC-704)

Description
| A lineup of three new types of universal
counters with high cost performance that features easy-to-use one
key, one action, the user-friendly display guide and calculation
functions support any application. The SC-7207/SC-7206/SC-7205 universal
counters provide full capabilities including frequency, period,
time interval, pulse width, phase, frequency ratio, duty cycle,
event accumulation and peak voltage measuring, with simple operation.
They are suitable for R&D and technical training as a basic
measuring instrument as well as for production/inspection lines. |
