• Exclusive current sensor phase shift function lets you maintain accuracy even in high frequency, low power factor applications
|Current Sensor Phase Shift|
Current sensor phase shift is essential especially in high current situations in order to achieve optimal measurement precision. Current sensors typically exhibit gradually increasing phase error in the high-frequency region due to the characteristics of the sensor’s magnetic core and circuitry. Furthermore, differences in the design of various sensor models cause the magnitude of this error to vary.
The PW6001’s current sensor phase shift function uses sensor-specific phase error information to correct for error, thereby improving phase characteristics in the high-frequency region and reducing power measurement error. Phase shift correction is conducted with a 0.01° resolution in order to measure power even more accurately.
|0.1 Hz to 2 MHz frequency bandwidth|
Power measurements across wide bandwidths are required for supporting high-speed switching devices such as SiC. Compared even to the Hioki 3390 Power Analyzer, the PW6001 is engineered with 10x the frequency band and sampling performance.
|High-speed sampling of 5 MS/s for true frequency analysis|
Measurements based on sampling theorem are required to perform an accurate power analysis of PWM waveforms. The Hioki PW6001 features direct sampling of input signals at 5 MS/s, resulting in a measurement band of 2 MHz. This enables analysis without aliasing error
|Fast, simultaneous calculation functions achieved with Power Analysis Engine II|
All measurements, including period detection, wideband power analysis, harmonic analysis, and waveform analysis, are digitally processed independently and with no effect on each other. Fast calculation processing is used to achieve a data update speed of 10 ms while maintaining maximum
|Strengthened resistance to noise and temperature fluctuations in the absolute pursuit of measurement stability|
The custom-shaped solid shield made completely of finely finished metal and optical isolation devices used to maintain sufficient creepage distance from the input terminals dramatically improve noise resistance, provide optimal stability, and achieve a CMRR performance of 80 dB/100 kHz. Add the superior temperature characteristics of ±0.01%/°C and you now have access to a power analyzer that delivers top-of-the-line measurement stability.
|Analyze waveforms without an oscilloscope|
