All specifications are subject to change without notice.
Note 1: Line impedance range representative of most common 50 Ω (100 Ω differential) and 45 Ω (90 Ω differential) lines ± 20% mismatch.
Note 2: Line impedance range covers all typical transmission line or test node impedances in the range 0 Ω to 100 Ω (200 Ω differential).
Note 3: CAUTION: When using AC coupled probes, to avoid damage to the connected instrument ensure that it can withstand transient voltage equal to the DC bias of the test node divided by the nominal probe ratio.
Note 4: Typically it will be possible to scale results at the connected instrument to correct for this small nominal error.
Note 5: WARNING: For peak voltage above 46.7 V, to ensure that touch current lies within acceptable limits of EN61010: 2010, pulse or burst width must not exceed 500 ns and pulse mark:space must remain below 2%.
Note 6: CAUTION: To avoid damage to the probe, RMS voltage over the pulse period must remain within specified probe rating.
Note 7: Probes having unmatched output impedance will not absorb pulse aberrations that reflect off mismatch at the connected instrument input. Pulse fidelity and flatness are therefore more dependent on good instrument match.
