Digital Filter Options
Lorch Microwave can provide a wide selection of tunable
bandpass and bandreject options, including digitally con-
trolled filters. Standard bandpass and bandreject tuners can
be configured to provide digital frequency control. Tuning is
accomplished by utilizing a servo-type stepping motor to
drive the gear assembly.
A programmable microprocessor-based system is used.
Many control logic options exist including serial, RS-232,
RS-422, IEEE-488, and BCD.
