These accessory items are used to combine a DC offset or bias with a pulse signal
from a pulse generator. (These are intended as pulse-mode accessories for Avtech pulse
generators, and have not been characterized in the frequency domain for CW use.)
Many Avtech pulse generators already have a bias-tee circuit built in, or offer it as an internal option.
These models can often be customized to handle different combinations of DC currents, pulse voltages, and pulse widths.
See also the AVX-S selection of bias insertion units, which include a high-speed socket for a diode device.
