Boonton Power Sensor - Manual (Page 11)

5107xA Series of RF Sensors
The “A” series sensors were created to improve production calibration results. These
sensors possess the same customer specifications as the non-A types (i.e.: 51075 and
51075A), however, the utilization of new calibration methods enhances the testing
performance over previous techniques. In doing this, Boonton can provide the customer
with a better product with a higher degree of confidence.
The “A” series sensors utilize “Smart Shaping” technology to characterize the linearity
transfer function. This is accomplished by performing a step calibration to determine the
sensors response to level variations. The shaping characteristics are determined during
the calibration and then the coefficients are stored in the data adapter that is supplied with
the sensor. This provides improved linearity results when used with the 4230A and 5230
line of instruments with software version 5.04 (or later).
Instruments that are equipped with step calibrators such as the 4530 already perform this
function when the Auto Cal process is performed. For these instruments an “A” type
sensor performs the same as a non-“A” type and no discernable difference is realized.
