Typical Responsivity vs. Frequency
Detectortype : PYD 1388
Date of Issue: 25.08.03
Unless specified differently, all data refer to 25° C:
Responsivity is measured within spectral range 7 - 14 µm as per fig. 3 at 1Hz.
Electrical balance (match) is measured with same test set up as responsivity, both elements
exposed to radiation. A percent value is calculated as
After a 10 minute settling time, noise is monitored for the duration of 1500 sec. at a
temperature of 50° C, shut from infrared energy, electrical bandwidth of 0.4 to 10Hz.

The sensing elements are connected to built-in FET in source follower circuit, connections
"Drain-Source-Ground". It is recommended to use a load resistor of 47 kΩ.
