not used (value 0)
Bits 0 and 7 are not used and always have the value 0.
Please note that the R&S
ESR reports any key pressed on the front panel rather than
only the unit keys if bit 1 was enabled.
Another difference is the behavior of bit 6 when using the STB? query. On the HP ana-
lyzers this bit monitors the state of the SRQ line on the bus. On the R&S
ESR this is
not possible. Therefore this bit is set, as soon as one of the bits 1 to 5 is set. It won't be
reset by performing a serial poll.
