The RD3023/3024/3025 Series
recorders are fast, high-performance
X-Y recorders, available in either
1- or 2-pen models. The
RD3023/3024 are size A3 X-Y
recorders, and the RD3025 is an A4
X-Y recorder. These recorders offer
high slewing speed and high
acceleration. The slewing speed
and acceleration of the 1-pen
model in the Y-axis is 2200 mm/s
(86.6 in/sec) 7.6 G, and 2000 mm/s
(78.7 in/sec) 5.1 G in the
X-axis (2-pen model is 7.0 G in the
Y-axis and 4.5 G in the X-axis).
Excellent phase and frequency
characteristics ensure precision
recording of fast-changing signals.
For optimal convenience, these
recorders come with easy-to-use,
felt-tip pen cartridges, a 10-position
offset input dial, 16 speeds of
internal time base (standard on
RD3023/3024, optional on
RD3025), remote control of sweep
start and reset, and pen lift by
external contact or TTL level
signals.
The arrangement of controls on the
front panel is neat and logical,
including convenient servo ON/OFF
polarity reversal switches, and
preamplifiers separated from the
input terminals for safety input
wiring. The noise performance
of these recorders is excellent,
eliminating the low-pass
filter switch.
