STAT:CHANnel Channel-Specific Channel Status Command/Queries
Description
The Channel Status group consists of a set of registers for each channel. Each channel
register set monitors all events for that channel and sums them into a corresponding
summary bit in the Event register of the Channel Summary group.
The following Channel Status registers are associated with each channel:
Condition Real-time (“live”) channel status.
Event Records all channel events that occurred since the last time the register
was read.
Enable Mask for selecting which bits in the Event register are allowed to be
summed into the corresponding channel bit of the Channel Summary
Event register.
Remember
The STAT:CHAN commands are channel specific. For the multiple electronic load first
send a CHANnel command to select the desired channel.

Command/Query Syntax
Command/Query
Function
STATus:CHANnel:CONDition?
Returns the binary value of the Channel Status Condition register, which
represents the present status. A condition exists if the corresponding bit = 1.
STATus:CHANnel[:EVENt]?
Returns the binary value of the Channel Event register, which latches 0-to-1
transition of the channel conditions the first time they occur. The Event bit
remains 1 even if the condition has since disappeared. Reading this register
resets it to zero.
STATus:CHANnel:ENABle
A mask that specifies which bits of the Channel Status Event register will be
allowed to be summed into the appropriate channel bit of the Channel Summary
register. Set the bit to 1 to enable the condition. Program MAX to enable all
allowable bits or MIN to disable them.
STATus:CHANnel:ENABle?
Returns the binary mask value of the Channel Status Enable register.
Returned Parameters
< NR1 > Register binary value.
Examples
STAT: CHAN? Returns the value of the Event register in a single electronic load or of
the presently addressed channel Event register in a multiple electronic load.
