Built-in radar and wireless presets
Begin testing faster; the X-Series power sensor comes with built-in radar and wireless presets
for common signals such as DME, GSM, EDGE, WCDMA, WLAN and LTE.
Gamma correction
In an ideal measurement scenario, the reference impedance of the power sensor and device-
under-test (DUT) impedance should equal the reference impedance (Z0); however, this is
rarely the case in practice. The mismatch in impedance values results in a portion of the signal
voltage being reflected, and this reflection is quantified by the reflection coefficient, gamma.
Using the gamma correction function, users can simply input the DUT’s gamma into the
X-Series power sensor using SCPI commands or the Keysight BenchVue software. This will
remove the mismatch error, yielding more accurate measurements.
S-parameter correction
Additional errors are often caused by components that are inserted between the DUT and
the power sensor, such as in base station testing where a high power attenuator is connected
between the sensor and base station to reduce the output power to the measurable power
range of the sensor. The S-parameters of these components can be obtained with a vector
network analyzer in the touchstone format, and inputted into the sensor using SCPI commands
or through the Keysight BenchVue software. This error can now be corrected using the X-Series
power sensor’s S-parameter correction function. The sensor will behave as though it is
connected directly to the DUT, giving users highly accurate power measurements.
Compact and portable form factor
The X-Series power sensor are standalone sensors that operate without the need of a power
meter or an external power supply. The sensors draw power from a USB/LAN port and do not
need additional triggering modules to operate, making them portable and lightweight solutions
for field applications such as base station testing. Simply plug the sensor to the USB/LAN port
of your PC or laptop with Keysight BenchVue software’s BV0007B Power Meter/Power Sensor
Control and Analysis app and start your power measurements.
