Couldn't get a rental unit at short notice, and there is a lead time on a new unit. Unfortunately the High Frequency response and current is important so it sounds from Doug's email that it will have to be the 2877 as no substitute
Rich From: Ken Javor [mailto:[email protected]] Sent: Tuesday, August 20, 2019 6:08 PM To: [email protected] Subject: [External] Re: [PSES] Pearson RF Current Probe I have a Pearson Model 2877 and used it on a project where the electric field was quite strong and the current very minute, so I needed much more electric field shielding than afforded by the typical current probe design. This was after copper taping a conventional current probe (1.25" window diameter so naturally larger seams compared to the Model 2877's 0.25" window diameter) with 6 dB higher transfer impedance (into 50 Ω), and seeing nothing but the electric field coupling. The Model 2877 gave me the electric field shielding I needed to make the measurement. In terms of frequency coverage, the only way I know to get that wide is with a Hall-effect oscilloscope probe. But it won't have the dynamic range. And likely not the E-field shielding (although I have never measured that). The 2877 is quite inexpensive - I'm curious why a substitute is necessary?
