200utput current and power are rated into a
one-half ohm
load.
21Higher output powers can be accomodated
by
using a booster. Contact ILX Lightwave for further information.
22~roadband noise is measured at
100
mA output current, over a bandwidth of
10
Hz
-
10
MHz.
23~emperature control range depends primarily on the
type
of thermistor and
TE
module used. The range can
be
extended higher and lower
by
selecting appropriate components. See Appenhx
B
for more details.
