FURTHER SETTINGS IF REQUIRED
Ranging. By default, the PWRVIEW software sets up the PA3000 current range in Auto-Up-Only.
The Auto-Up-Only option ranges up the PA3000 until it finds the highest range where the input
signal is not clipped. This helps with setting the best range for the test. Otherwise, if the expected
peak currents are known, a manual range can be selected for higher accuracy. The manual range
can be selected for the selected shunt through the setup page under range options.
Bandwidth. For low power standby signals that have undesired high frequency components,
low bandwidth filters can be enabled. A low bandwidth 10 kHz filter is available through the setup
screen under the filter drop down option. Applying low pass filters might vary the RMS values of
voltage, currents, and power as high frequency components affect the RMS values.
AC Source. The IEC 62301 standby power full compliance test requires the AC source to be
very stable as detailed in the standard. The voltage and frequency are required to be within 1%
tolerance. In addition, the input voltage total harmonic content (VTHC) must be within 2% for
the first 13 harmonics and the voltage crest factor (VCF) must be within the 1.34 to 1.49 range.
Tektronix recommends using a stable external AC source that meets standard requirements
for the full compliance testing.
