NOTE
Overview
The 2050/60 X-Series wide dynamic range power sensors consist of six USB models and
seven LAN models:
– U2053XA USB average power sensor (10 MHz to 33 GHz)
– U2063XA USB peak and average power sensor (10 MHz to 33 GHz)
– L2051XA LAN average power sensor (10 MHz to 6 GHz)
– L2052XA LAN average power sensor (10 MHz to 18 GHz)
– L2053XA LAN average power sensor (10 MHz to 33 GHz)
– L2061XA LAN peak and average power sensor (10 MHz to 6 GHz)
– L2062XA LAN peak and average power sensor (10 MHz to 18 GHz)
– L2063XA LAN peak and average power sensor (10 MHz to 33 GHz)
The 2050/60 X-Series is capable of measuring the average and peak power of modulated,
pulsed, and continuous wave (CW) signals in 10 MHz to 33 GHz frequency range and
–70 dBm to 26 dBm power range.
The L2050/60 Series LAN power sensor is capable of long distance remote monitoring of
up to 100 meters via the Power over Ethernet (PoE)/LAN connectivity. The PoE connectivity
is compliant to the IEEE 3 W, 802.3af or 802.3at Type 1 standard.
The typical LAN port on your PC or Keysight instruments is not able to power up the L2050/
60 Series LAN power sensor. The L2050/60 Series LAN power sensor must be connected to
a PoE port, which supplies the DC power required to power up the L2050/60 Series LAN
power sensor and to transfer data.

Theory of Operation
Figure 1-3 2050/60 X-Series sensor block diagram
The 2050/60 X-Series sensors utilize 4 planer doped barrier diode in a 4-path microwave
circuit that enables fast average power measurements over a wide dynamic range. The 4path network splits the input signal into a different power range for each of the 4 diodes
such that all of them can operate in their square-law region. Ensuring diode power sensors
operate within the square-law region means that they can convert RF power to voltage in a
linear manner, regardless of the signal being measured. A single diode sensor square-law
behavior may only provide perhaps 40dB of fast dynamic range. Each of the diodes has
their own signal conditioning and analog to digital convertor which allow subsequent
digital processing to select the best diode for further processing. This in turn presents a
user experience indistinguishable from a single high dynamic range square-law power
sensor.

As a truly universal power sensor, it has features that allow different kinds of power
measurements to be made. Primarily it operates as an average power sensor and
traditionally this type of measurement means that an instrument will output a numeric
result at some rate determined by the instrument. In AVERAGE mode the sensor enables a
chopper amplifier circuit that allows low level signals to be measured in the presence of
low frequency noise. This chopper circuit operates by modulating the signal prior to
amplification; the modulation takes the form of passing or negating the signal for halfperiods of the chopper signal. Recovering the original signal within the digital processing is
achieved by averaging the ‘passing’ half-period samples together with the negated
‘negating’ half-period samples, to provide a new answer once for each period of the
chopper. The corresponding “de-chopping” is carried out in digital section to allow proper
correction and measurement of input signal. The chopper stabilization circuit essentially
remove the offset and low frequency noise contribution of the signal condition stages from

affecting input signal. In this series of sensor, the chopper concept is extended to allow the
user to set an ‘aperture’ over which averaging is calculated. This aperture is selectable in
100ns resolution and provides a powerful mechanism for precisely tuning the instrument to
the signal being measured. In addition to allowing the aperture to match a particular epoch
of the RF signal, for example setting the aperture equal to a multiple of the modulation
frequency in an AM signal, there is the ability to precisely trigger the occurrence of each
measurement. This allows synchronization between the device under test and the
measurement system.
Sometimes it is necessary to examine the time varying characteristics of the power
envelope. This allows measurements of pulse duration time or pulse period for example.
This series of sensor has NORMAL measurement mode to provide 20MHz sampling of the
power envelope. In common with AVERAGE mode, the best diode from the 4 ranges is
selected transparently within the digital processing. In contract to AVERAGE mode, no
chopper switching is performed and the signal path is a direct coupled differential
amplifier. The analog signal conditioning allows the load resistor and the low pass filter
characteristics to be adjusted. Changing the load resistor also changes the response level
(V/W) of the diode detector and its video bandwidth. Changing the load capacitance will
affect the bandwidth but not the response level. Used together, these controls enable
reduced noise on the measurement for low level signals at the expense of video bandwidth.
A high speed trigger Input and trigger output are also present in each sensor to allow
proper synchronization between test instruments. Besides that, Average and Normal mode
do support internal level trigger mode on top of external trigger mode. This allows flexibility
in triggering on different input signal over a wide dynamic range.
A high speed acquisition and processing engine is also present in the sensor to enable a
complex calibration scheme to track the performance of various modes across frequency,
input power and temperature. The robust back end system also allows 2050/60 X-Series to
be paired with either conventional USB or LAN based interface. With a LAN based
interface, the prefix “U” is replaced with “L”.

– Static IP (Manual mode)
The default LAN operating mode of the L2051XA/52XA/53XA/61XA/62XA/63XA is
Dynamic IP.
Dynamic IP and Auto IP are enabled on the L2051XA/52XA/53XA/61XA/62XA/63XA
shipped from Keysight. This allows the L2051XA/52XA/53XA/61XA/62XA/63XA to
automatically obtain an address on the network.
The L2051XA/52XA/53XA/61XA/62XA/63XA communicates with the DHCP server to
obtain the LAN interface configuration. If the DHCP server is not detected, then either the
DHCP server is not present or it does not allow the L2051XA/52XA/53XA/61XA/62XA/
63XA to obtain an IP address. The L2051XA/52XA/53XA/61XA/62XA/63XA will then try to
obtain the LAN configuration using AutoIP if enabled, otherwise the L2051XA/52XA/53XA/
61XA/62XA/63XA will try to use the static IP set in the L2051XA/52XA/53XA/61XA/62XA/

Quick start example to set up a measurement in the Trace view
The following example guides you on how to set up a basic peak power measurement for
RF pulses via BenchVue.
The default power meter mode is Average only. It will change to the Normal mode when
the Trace view is selected. As the Normal mode provides a lower dynamic range, the
measurable power range will automatically narrow down.
To obtain a wider dynamic range for low power measurements (< –40 dBm), you will need
to set to the Average only mode. If the measurement is in the Trace view, a warning
message will appear as the Trace view is only applicable for the sensor's Normal mode.
It is assumed that the 2050/60 X-Series is already connected to a signal generator.
1 Set up the signal generator as follows:
– Pulse period: 500 μs
– Pulse width: 100 μs
– Amplitude: 5 dBm
–Frequency: 1 GHz
– Pulse: Enabled
2 Turn on the RF output of the signal generator. Launch the BenchVue Power Meter

Channel Setup
(in the Trace view)
– Set the video averaging to average repetitions of a triggered signal, with a count of 1 to 256 in mul tiples of 2n. With video
averaging, the average of a number of acquisitions is calculated to smooth the displayed trace and reduce apparent noise.
The measurement requires a continuously repeating signal.
– Set the video bandwidth.
The Low, Medium, and High pass band shapes achieved by the video bandwidth settings provide flat filter responses with
very sharp cut-off points by applying d igital signal processing techniques to ensure accurate power measurement within
the specified band.
When the video band width is set to Off, it removes all digital signal cond itioning. This provides less than 3 dB roll-off

Measurement Gates
A measurement gate allows measurements to be performed on particular sections of the
input signal. The gate is defined by a start time relative to the trigger event and a duration.
Signal samples acquired during the time interval specified by the gate are used for the
measurements in that gate. A system of up to four independent gates is provided.
Below is an example of a 4-gate setup to perform the following measurements
simultaneously:
Average power level of the pulse Gate 1, average measurement
Average “off” power level ahead of the pulse Gate 2, average measurement
Peak-to-average ratio Gate 1, peak-to-average measurement
Pulse droop
Gate 3, average measurement, minus Gate 4, average
