Get the same accuracy and performance in thermal vacuum (TVAC) chambers with the world’s first TVAC-qualified power sensor. With best-in-class long-term drift performance, the LAN power sensors are ideal for fault detection and monitoring of satellite systems. And with LAN/Power over Ethernet (PoE) connectivity, a first in the industry, you can perform long-distance, remote monitoring of satellite systems with ease and confidence.
Thermal vacuum compliance
The U2049XA Option TVA (thermal vacuum option) and L2065/66/67XT are LAN TVAC compliant power sensors that can be used within a thermal vacuum chamber. These sensors have been meticulously designed by selecting components with minimum outgassing properties. Each of these sensors are also subject to temperature cycling in a vacuum chamber to stabilize the materials and to remove outgassing particles.
| LAN Model | Description | Frequency Range | Power Range | Connector Type |
| U2049XA (Option TVA) | Wide dynamic range peak and average power sensor with thermal vacuum option | 10 MHz to 33 GHz | −70 to +20 dBm | 3.5 mm (male) |
| L2065XT | Wide dynamic range peak and average power sensor with thermal vacuum compliance | 10 MHz to 53 GHz | −70 to +20 dBm (10 MHz to 50 GHz) −70 to 0 dBm (> 50 GHz to 53 GHz) | 2.4 mm (male) |
| L2066XT | Wide dynamic range peak and average power sensor with thermal vacuum compliance | 10 MHz to 54 GHz | −70 to +20 dBm (10 MHz to 50 GHz) −70 to +15 dBm (> 50 GHz to 54 GHz) | 1.85 mm (male) |
| L2067XT | Wide dynamic range peak and average power sensor with thermal vacuum compliance | 10 MHz to 67 GHz | −70 to +20 dBm (10 MHz to 50 GHz) −70 to +15 dBm (> 50 GHz to 54 GHz) −70 to +10 dBm (> 54 GHz to 67 GHz) | 1.85 mm (male) |
Super-fast measurement speed
The X-Series power sensors take up to 50,000 super-fast readings per second (in fast/buffer mode/ average mode), a ten times improvement over Keysight’s previous sensor offerings, allowing test engineers to increase test throughput capacity and reduce the cost of test, especially in high volume manufacturing environments such as mobile chipset manufacturing.
This measurement speed is fast enough to measure every continuous pulse without leaving time gaps in between measurement acquisitions. While conventional sensors only provide a snapshot of continuous pulses, leaving dead time where a glitch could slip by unnoticed, the X-Series power sensors measures continuously in real-time and keep pace with very fast pulses, up to 10 kHz PRF. Users are also able to fully control which portion of the signal is measured and what throughput they can expect because the aperture duration precisely defines the maximum measurement speed as 1/aperture duration. For example, setting the aperture duration to 20 μs offers 20 μs of measurement time per reading, equaling a measurement speed of 50,000 readings per second.
Built-in radar and wireless presets
Begin testing faster; the X-Series power sensors come with built-in radar and wireless presets for common signals such as DME, GSM, EDGE, WCDMA, WLAN and LTE.
Broadband coverage for any modulated signal formats
The X-Series power sensors make accurate average or time-selective average power measurements of any modulated signal and cover all common wireless signals such as 5G, LTE, LTE-Advanced with 100 MHz bandwidth, and WLAN 802.11ac with 80/160 MHz bandwidth. A 4-path diode stack design with parallel data acquisition paths offers seamless range transition with high accuracy and repeatability. This design enables all the diodes to operate in their square law region, allowing the X-Series power sensors to function like thermocouple power sensors to provide accurate average power for broadband modulated signals.
20 automatic pulse parameter measurements
The U2049XA (Option TVA), U/L2060 X-Series and L2065/66/67XT peak and average power sensors offer simultaneous pulse parameter characterization of up to 20 pulses within a single capture. Individual pulse duration, period, duty cycle, rise time, fall time and other pulse parameters can be queried through the following SCPI codes:
TRACe:MEASurement:PULSe[1-20], and TRACe:MEASurement:TRANsition[1-20].
Together with a system’s rise time and fall time of 100 ns and video bandwidth of 5 MHz, the X-Series peak and average power sensors enable a minimum measurable pulse width of 250 ns with its sampling interval of 50 ns.
Users can quickly and accurately measure the output power and pulse parameters of pulses for radar pulse component design or manufacturing.
