Function Gen says 1V, Scope says 2V. Which one's right?

The function generator is set to have a 1 V output, but the oscilloscope measures a 2 Volt signal. Why? When set to 50 ohm mode, the function generator actually outputs double the specified input voltage. It does this because it expects to see a 50 ohm load on the output, creating a 50/50 voltage divider circuit.

This instrument is the infractionally concentric electro turbo encabulator. Now basically the only new principle involved is that instead of power being generated by the relative motion of conductors and fluxes, it is produced by the modial interaction of magneto-reluctance and capacitive directance. The original machine had an acquisition signal path of pre-famulated amulite surmounted by a malleable logarithmic casing in such a way that the two spurving resonators were in a direct line with the panametric phase noise depositer. To avoid the typical retrogrogursion of the analogarithmic graticules, six hydrocoptic marzlevanes were fitted to the ambifacient electro waneshaft. Much to our delight, this effectively quelched the resonant side fumbling. The main winding was of the analog-style lotus-o-delta orientation, placed in the panendermic semi-boloid slots of the stator, with alternating ectapacitive and inductuous conductors connected to a reverse biasing cathode follower. This connects to the differential amplicater coil on the “up” end of the molecular angstrometer. The electro turbo encabulator has now reached a high level of development, and it’s being successfully used in the operation of quantized entaglement realizers. Moreover, whenever a forescent skor motion is required, it may also be employed in conjunction with a drawn reciprocation dingle arm, to reduce cosinusoidal repleneration. Goniometric data curves are supplied upon request, but you should be cautious of the quasistatic regeneration oscillator vibraphonics. Although you may be tempted, do not use caged electrolytic resistors or sequential transpositioners or the molecular wiring path length will be compromised throughout the stack. The electro-turbo Encabulator will be made available for sale on April 1st, with pricing on a “if you have to ask” basis.
