Questionable Status Event Enable Register
The Questionable Status Event Enable Register lets you choose which bits in the Questionable Status
Event Register will set the summary bit (bit 3 of the Status Byte Register) to 1. Send the command
:STATus:QUEStionable:ENABle <num>
where
<num>
is the sum of the decimal values of the bits
you want to enable.

Description
0 0
R.P.P Tripped
: A 1 in this bit position indicates that the
reverse power protection is tripped (Agilent ESA models
E4401B and E4411B only). Reverse power protection is
“overload” protection for the tracking generator.
1 2 Source Unleveled : A 1 in this bit position indicates that
the source (tracking generator) output is unleveled.
2 4
Source LO Unleveled
: A 1 in this bit position indicates
that the local oscillator (LO) in the source (tracking generator)
is unleveled.
3 8
LO Unleveled
: A 1 in this bit position indicates that the
analyzer local oscillator (LO) is unleveled.
4 16 50 MHz Osc Unleveled : A 1 in this bit position indicates
that the 50 MHz amplitude reference signal is unleveled.
5 32 Reserved : This bit is not used by the analyzer, but is for
future use with other Agilent products.
6 64
Input Overload Tripped
: A 1 in this bit position
indicates that the input overload protection is tripped (Agilent
ESA models E4401B and E4411B only).
7 128 Unused : This bit is always set to 0.
8 256 LO Out Unleveled : A 1 in this bit position indicates that
the first local oscillator (LO) output is unleveled. (Agilent
ESA model E4407B option AYZ, External Mixing, only).
9 512
Unused
: This bit is always set to 0.
10 1024 Unused : This bit is always set to 0.
11 2048 Unused : This bit is always set to 0.
12 4096
Unused
: This bit is always set to 0.
13 8192 Unused : This bit is always set to 0.
14 16384 Unused : This bit is always set to 0.
15 32768
Always Zero (0)
: This bit is always set to 0.
