Ripple Noise Meter
RM-103
Ripple Noise Meter which can measure p-p Ripple Noise, p-p Noise
of Switching Power Supply by digital Measurement. (up to 100MHz).
Ripple Noise or Noise
Measurement has been though as trouble making, because Oscilloscope
won't detect peak of Ripple Noise or Measured data may be changed if
an Operator read such data with an Oscilloscope. Actually some noise
measurement tools are available but these never covers faster Ripple
and Noise more than 50MHz. Using narrow band tool makes no sense for
high speed noise which can gave undesired effect for equipments.

-
AC
Ripple Noise and Switching Ripple
can be measured independently.
-
Human
reading errors can be completely eliminated.
-
Only
one Ripple Noise Meter which
conforms to the Standard of EIAJ ,
Electronic Industries Association of Japan
-
Ripple Noise Meter can measure faster
noise up to 100MHz
-
Automatic

New Automated Measurement
method
Now you
can terminate such trouble completely. RM-103 can measure p-p
Ripple Noise and p-p Noise accurately and automatically by GPIB and
manually.
With SC-82 Scanner, Multiple Input up to 16
channel can be applied .
You can select Input channel of SC-82
via RM-103 by GPIB for p-p Ripple Noise and p-p Noise
measurement.
Also you can add DP-100 Differential Probe to eliminate
Common Mode Noise.
Of course all these family covers wide band range up to 100MHz
