O2 sensor reading

Hi, Guys.
Can anyone confirm what kind of reading I should get from a 2001 HO 4.0L upstream O2 sensor?
The manuals I've found are either incomplete or misleading. One says it's a resistance reading, but I doubt it because there's no +5V input. Just the two white wires for the heater and two other: one signal, one ground.
My guess is between 0 and 1V switching about 5 times/sec. Right?

Thanks in advance.
