Hi all-
I have a DSA815-TG.
I also recently picked up the tekbox near field probes that Dave semi-reviewed in a mailbag segment:
http://www.tekbox.net/test-equipment/tbps01-emc-near-field-probes-tbwa2-wideband-amplifierI have the TBWA2/40db set with the 40db amplifier.
Is there any risk in connecting these directly up to (with or without the amplifier) the front-end of the DSA815?
I have a full-set of mini-circuits 2W attenuators, but would prefer to not use them unless necessary.
I ask because I've seen a few posts recently mentioning things like static electricity frying the front-end of SA's. The DSA815 has a blocking cap on the frontend, but I don't know if that ameliorates most of the risk in this context.
I also had one of the near field probes hooked up through the 40db amplifier, and I was trying to demodulate FM radio into the headphone jack (just for fun). The DSA818 would sporadically report "412 DA overrange due to volume adjustment in FM.". I have no idea what this error means, and I couldn't find any references to it on the web. Hope it doesn't mean I broke something.
I know essentially nothing about RF and bought the DSA815 mainly as a learning tool, so be gentle (if possible).
Thanks,
Dustin
