| Clamp Sensors (For Oscilloscope/ MEMORY HiCORDERs, DC to 100MHz wide-band for observing waveforms) |
CLAMP ON PROBE 3273-50 |
|
|
|
 |
Max. rated voltage to earth
CAT I 300 V |
|
 |
|
|
|
|
|
| Wide-band current probe allows direct input to oscilloscope |
|
- Wide band: DC to 50 MHz (-3 dB)
- High S/N characteristic enables measuring ultra low mA-range current waveforms
- Connects directly to oscilloscope BNC input terminal
- Connects directly to the MEMORY HiCORDER to provide waveform monitoring
- An optional power supply is available for use with oscilloscopes that do not provide probe power
|
|
| Note: Connect and power up Clamp-on sensor to use in combination with the oscilloscope, or the MEMORY HiCORDER |
