Well, I cave in and bought a Fluke pug

I wanted a good thermocouple based ac voltmeter for a while and found this Fluke 8921A for not a lot of money (thank you Gixen for allowing me to snipe my way out

). The Fluke 892X series was introduced around 1978 and was based on their new hybrid true rms converter. It was a direct competitor to the HP 3403C and was apparently cheaper when introduced to the market (1000$ vs 2600$).

From the side you can surely appreciate the nice yellowing, typical on Fluke instrument from that vintage.

Since I'm not necessarily interested to remove the shield, the inside is particularly uninteresting.

I like the fact that you can directly adjust the dBm reference on the front panel and don't need to do the conversion yourself. The meter read a bit low though and will probably need to be recalibrated and adjusted.

Still provide good performance at 20Mhz.

-3dB point is around 41MHz.

On the 2mV range, sensitivity is really good and can go as low as -65dBm (125uVrms).
