R3132 Series Spectrum Analyzer Operation Manual
4.2.8 Status Byte
4-20
The table below explains the meanings of the bits in the status byte register.
Bit Functional definition Description
7 OPR The OPR bit is a summary of the standard operation status
register.
6 MSS The RQS bit is true when the MSS bit of the status byte
register is set to 1. The MSS bit is the summary bit for the
entire status data structure.
The serial poll cannot read out the MSS bit. (However, the
MSS bit is understood to be 1 when the RQS bit is 1.)
To read the MSS bit, use the common command *STB?.
The *STB? command can read out bit 0 to 5 and bit 7 of
the status byte register and the MSS bit. In this case,
neither the status byte register nor the MSS bit can be
cleared.
The MSS bit cannot become 0 until all the unmasked
factors in the status register structure have been cleared.
5 ESB The ESB bit is a summary of the standard event register.
4 MAV Summary bit for the output buffer.
This instrument does not use this bit.
3 to 1 This is always 0.
0 UCAL This is set to 1 when an signal level error occurs because
the sweep is too fast.
