Should you decide to go the DIY route for the LISN, check out the project in the Elektor magazine recently:  https://www.elektor.com/elektor-dual-dc-lisn-150-khz-200-mhz

The R&S FPC does have an optional preamp (FPC-B22 option) which is included in the FPC-COM2 kit.

With the preamp on, sensitivity is increased to about -165 dBm (typ).  We also spec TOI, SHI, and DANL with and without the preamp enabled.

For people who are new to the FPC (and spec ans in general), there are about a half dozen basic "Getting Started with the FPC" videos in the T&M Fundamentals Playlist on the R&S YouTube channel:

There's also a video about LISNs (but probably too basic for you)



The next time I'm working on FPC-related videos, I'll do a few on EMI/EMC testing :)

The downside of the FPC1500 is that scalar measurements have a lower frequency of 2MHz. That is slightly high for dower power distribution network measurements. 100kHz would be nicer as a lowest frequency.

Oh thanks for clearing this up as the OP for his EMI needs should get the Tekprobe and preamp EMI set or purchase the B22 option and only the Tekprobe $199 EMI probes.

That certainly is an additional cost in getting the R&S whereas all Siglent SA/VNA's come equipped as standard with a preamp.
