AD8327
Transmit Enable and Sleep Mode
The Transmit Enable and Transmit Disable buttons select the
mode of operation of the AD8327 by asserting logic levels on
the asynchronous TXEN pin. The Transmit Disable button
applies Logic 0 to the TXEN pin, disabling forward transmis-
sion while maintaining a 75 Ω back termination. The Transmit
Enable button applies Logic 1 to the TXEN pin, enabling the
AD8327 for forward transmission. Checking the “Enable
SLEEP Mode” checkbox applies logic “0” to the asynchronous
SLEEP pin, setting the AD8327 for SLEEP mode.
Memory Functions
The MEMORY section of the software provides a way to
alternate between two gain settings. The “X->M1” button
stores the current value of the gain slide bar into memory
while the “RM1” button recalls the stored value, returning
the gain slide bar to the stored level. The same applies to the
“X->M2” and “RM2” buttons.
