Definitions
• Specifications describe the performance of parameters covered by the product warranty
(temperature – 0 to 55 °C, unless otherwise noted.)
•Typical describes additional product performance information that is not covered by the
product warranty. It is performance beyond specification that 80% of the units exhibit
with a 95% confidence level over the temperature range 20 to 30 °C. Typical
performance does not include measurement uncertainty.
•Nominal values indicate expected performance, or describe product performance that is
useful in the application of the product, but is not covered by the product warranty.

Characteristics
Characteristics
The E444xxAU Option H37 reduces the level of residuals in the 37 KHz range. Option H37
provides a kit to reduce the level of residuals in the 37 kHz range by 10 dB. Refer to Figure
12 and Figure 13 on page 13.
Performance Tests and Adjustments
The tests outlined in this section are to verify the operation of the Option H37 and should
be used in conjunction with the standard PSA manuals. This section also includes the
equipment required.
37 kHz Spur Test
