YOKOGAWA WT1803 Three Input Element High Performance Power Analyzer

The Yokogawa WT1803 Three 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 WT1803 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: 3. 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.

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.

dBm
dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). Zero dBm equals one milliwatt. A 3 dB increase represents roughly doubling the power, a 3 dB decrease, the power is reduced by about one half.

Millimeter-wave
Millimeter-wave is a term that generally refers to frequencies of 26.5 GHz and above. That is where signal wavelengths fall below approximately 10 mm, and thus the terminology changes from centimeters to millimeters.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, remains fixed with the passage of time or with varying environmental conditions.
