YOKOGAWA WT1802 Two Input Element High Performance Power Analyzer

The Yokogawa WT1802 Two Input Element High Performance Power Analyzer has innovative functions that help improve measurement efficiency; Motor, Inverter, Lighting, EV/HEV, Battery, Power Supply, Aircraft, New Energy, Power Conditioner. Direct input of measurement signals makes it possible to measure very small current that can hardly be measured with a current sensor. The WT1802 provides a direct input voltage range from 1.5 V to 1000 V (12 ranges) and a direct input current range from 10 mA to 5 A (9 ranges) or from 1 A to 50 A (6 ranges). The frequency lower limit has been reduced to 0.1 Hz from the previous 0.5 Hz (5-fold lower than the previous model) to meet the requirement for power measurements at a low speed. Furthermore, high-speed data collection at a data update rate of up to 50 ms has been inherited. In addition to normal measurement data, up to the 500th order harmonic data can be measured and saved simultaneously. The data update rate can be selected from nine options from 50 ms to 20 s. Specifications. Basic power accuracy (50/60Hz): 0.1% of reading + 0.05% of range. Power frequency range: DC, 0.1 Hz ~ 1 MHz. Input elements: 2. Voltage range: 1.5/ 3/ 6/ 10/ 15/ 30/ 60/ 100/ 150/ 300/ 600/ 1000 [V]. Current range (direct input): 10m/ 20m/ 50m/ 100m/ 200m/ 500m/ 1/ 2/ 5 [A] or 1/ 2/ 5/ 10/ 20/ 50 [A]. Current range (external sensor input): 50m/ 100m/ 250m/ 500/ 1/ 2.5/ 5/ 10 [V]. Guaranteed accuracy range for voltage and current: 1% to 110%. Basic voltage/current accuracy: +/-0.1%. Basic power accuracy: +/-0.05%. Frequency range: DC, 0.1Hz to 1 MHz. Voltage/Current frequency range (-3 dB, typical): 5 MHz. Sampling speed: approximately 2 MS/s. Data update rate: 50 m, 100 m, 200 m, 500 m, 1, 2, 5, 10, 20 [sec]. Line filter: OFF, digital filter 100 Hz to 100 kHz (100 Hz step) analog filter 300 kHz, 1 MHz. Frequency filter: OFF, 100 Hz or 1 kHz. Fundamental frequency of the PLL source: 0.5 Hz to 2600 Hz (internal sampling clock), without external sampling clock function.

*This is a Web introductory price for one calibration of the YOKOGAWA WT1802. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
