Schwarzbeck software.
t
Fast 100% CISPR Quasipeak, CAV and
CRMS measurement with VARISCAN.
For many decades, most of the
interference measuring receivers were
used in laboratories. They were operated
manually using their front panel. This type
of operation including front panel control
will still be there in the future, but PC-
control gives value added measurement
because of increased speed and better
documentation. The unique r. f. and
analogue circuits of the FCKL 1528 give
precise measurement with or without PC-
control. The receiver comes complete for
EMI-measurement, but can be equipped
with useful options.
Characteristics of the FCKL 1528
Unique R.F. - circuitry
u
Attenuator with r.f.-relays uses resistive
Π
-attenuators with 1 dB steps. Total
resistive attenuation is 95 dB.
u
Switchable 10 dB high-power-attenua-
tor with 10 W for safe measurement
with L.I.S.N.s up to 4 x 400 A.
u
5 Input filters. Shape factors optimised
for EMI - measurement.
u
CISPR standard filters with 200 Hz and
9 kHz / - 6 dB. Filters are classic
double tuned band filters.
u
Integrated 25 Hz / 100 Hz Pulse-
standard for CISPR Band A and B
similar to IGLK 2914 for calibration.
Error is compensated by a EPROM list.
u
Integrated (optional) tracking generator
