Recall attributes

Recall attribute

Description

measurefunctions An array (a LUA table) of strings indicating the function measured

for the reading (Current, Voltage, Ohms or Watts).

measureranges An array (a LUA table) of full scale range values for the measure

range used when the measurement was made.

readings An array (a LUA table) of the readings stored in the reading buffer.

This array holds the same data that is returned when the reading

buffer is accessed directly, i.e., rb[2] and rb.readings[2] are the

same value.

sourcefunctions An array (a LUA table) of strings indicating the source function at

the time of the measurement (Current or Voltage).

sourceoutputstates An array (a LUA table) of strings indicating the state of the source

(Off or On).

sourceranges An array (a LUA table) of full scale range values for the source

range used when the measurement was made.

sourcevalues If enabled, an array (a LUA table) of the sourced values in effect at

the time of the reading.

statuses An array (a LUA table) of status values for all of the readings in the

buffer. The status values are floating-point numbers that encode

the status value into a floating-point value (see

Table 7-7).

timestamps An array (a LUA table) of timestamps, in seconds, of when each

reading occurred. These are relative to the basetimestamp for

the buffer (

Table 7-3).

1. The default attribute is readings and can be omitted. For example, smua.nvbuffer1 and

smua.nvbuffer1.readings will both return readings from Channel A, buffer 1.
