Why am I getting a 1:500 ratio on a DP02-1K (or 1:5000 on a DP02-10K) instead of 1:1000 (or 1:10000 on a DP02-10K) as specified in the datasheet?

The output impedance of DP02-1K and DP02-10K is 50Ω. To achieve the specified ratio in the datasheet, use a 50Ω feedthrough terminator (we recommend our FTT1B model) or set the scope input to 50Ω.

Can I use a high impedance termination to improve resolution for low level measurements?

Yes, you may use the standard 1MΩ scope input or a higher-impedance multimeter or DAQ for DC and low-frequency measurements only. Short output cables are recommended.

Should I twist the input leads to partially reduce input inductance and get more accurate HF measurements with less ringing?

It depends on the source impedance, slew rate, and resonance of the entire test setup. In some cases, it may help; in others, it may not. For most measurements, you will not notice an improvement when you twist the input leads. Our probes have low input capacitance, and the input resonance is typically above 100MHz.

What is your standard warranty?

Our standard warranty for all high-voltage differential probe models is 3 years from the delivery date. An extended warranty is also available.

I need to integrate your probes into our systems. What mounting options are available?

We offer three mounting options for our probes inside systems. The first option is to use the holes on the bottom of the probes: 5 x 6-32 screws for DP02 series probes (and 6 x 10-32 screws for DP20 and DP30 series probes). The second option is to use the DP02-FA mounting flange with 4 x 10-32 or 4 x 5mm screws along the probe width. The third option is to use the DP02-FB mounting flange with 4 x 10-32 or 4 x 5mm screws along the probe length.
