Probe Component Description
High-Voltage Differential Input Cable
Used to measure the input voltage signal after connecting it to the
insulated plunger hook clip. It can be extended with the extender leads
(approx. 1 m). When using the extender leads, the frequency of the signal
under test should be below 5 MHz.
Max. Differential Mode Input Voltage
1500 V (DC + peak AC)
Overrange Indicator
When the voltage under test exceeds the probe range, the overrange
indicator lights on.
Attenuation Switchover Button
Press this button to switch over between the voltage range (attenuation)
settings of the probe. For the PHA series probe, two attenuation ratios are
available: 500X and 50X.
50X indicates that the max. measurement voltage is 150 V.
500X indicates that the max. measurement voltage is 1500 V.
Bandwidth Switchover Button
Press this button to switch over between the bandwidth. The PHA series
probe supports two bandwidths.
FULL: indicates the full specified bandwidth of the probe. For
PHA0150, its full bandwidth is 70 MHz; for PHA1150, its full
bandwidth is 100 MHz; for PHA2150, its full bandwidth is 200 MHz.
5 MHz: When measuring the low-frequency signal, to reduce the
interference of the high-frequency signal, you can select the 5 MHz
bandwidth.
