Siglent SEM5022A 2 port Electronic Calibration Kit 100 kHz~13.5 GHz
The Siglent SEM5022A series electronic calibrator covering the frequency bands of 9kHz to 13.5GHz has a USB interface for communication and power supply, and has 3.5mm RF connectors. It is suitable for calibration and error correction of SHA800A series, SVA1000X series, SNA5000X series, SNA5000A series, and SNA6000A series vector network analyzers of Siglent Technology Co., Ltd
Efficient and accurate: Traditional mechanical calibration methods require the operator to connect and disconnect the instrument to be measured several times using calibration devices. This not only increases the calibration time, but also the frequency of operation and the probability of human error. When calibrating with electronic calibrators, the operator only needs to make one connection - at the very beginning, the port of the electronic calibrator is connected to the test port - which significantly reduces the number of connections made during the calibration process, making the process much simpler and more efficient. As the number of connections decreases, the probability of operator error is reduced, as is the probability of connector wear and tear, which in turn reduces the cost of port connector maintenance.
Quick and easy operation of the ECal module
Example setup:
The ECal module is connected to the vector network analyzer via a USB cable (supplied as an accessory) and the vector network analyzer then provides control and power via the USB cable. When connecting the electronic calibrator to the vector network analyzer, the vector network analyzer will automatically recognize the calibrator type, frequency range and connector type. When the connection is completed if the WAIT indicator (red) lights on, it means that the ECal module has not reached the normal operating temperature and needs to wait until the ECal reaches the normal operating temperature before it can be used; if the READY indicator (green) lights on, it means that the ECal module has reached the normal operating temperature and can be used normally. Disconnect: Simply disconnect the USB cable to stop the ECal module from working. Then simply disconnect the RF connector at ports A, B, C and D.

Definition of conditions:
Technical specification: Indicates guaranteed product performance for ambient temperature range, unless otherwise stated.
Typical value: Indicates typical performance at room temperature (approx. 25°C) for 80% of the test results with a 95% confidence level. The data is not guaranteed and does not include measurement uncertainty.
Nominal value: Indicates the expected average performance or the performance characteristics of the design, e.g. 50 Ω connector. The data is not guaranteed and is obtained from measurements at room temperature (approx. 25°C) and does not include measurement uncertainty
Operating temperature:
The temperature of the electronic calibrator must be within the following temperature range in order to meet the operating specifications. SEM5000A series: +15°C to +35°C and relative humidity must not exceed 75%
Characteristic performance:
The characteristic properties of ECal modules in Table 8-1 below, which mainly describes the residual errors in the different operating bands of the electronic calibrators.*
