IEEE-488 Reference
4-202
Line 10 Two commands in this program message; the first disables continuous initiation, and
the second places the Model 2001 in the idle state.
Line 20 Two commands in this program message; the first disables auto-zero, and the second
queries the state of auto-zero.
Line 30 Addresses the Model 2001 to talk.
Line 40 Displays the state of auto-zero (0; off).
Line 50 Re-starts the measurement process.
NOTE: When finished, be sure to re-enable auto-zero.

Response message: NORM, BURS, ASTR or SSTR
Description BURST and NORMal
These parameters are used to specify the acquisition method for storing readings in the buffer.
With the NORMAL method, readings will be stored at a rate that is determined by how the in-
strument is configured (i.e. integration period, resolution and filter).
When BURSt acquisition is selected, the Model 2001 is automatically configured for optimum
speed (The instrument’s previous configuration is restored when normal acquisition is again se-
lected). The burst mode configures the buffer for compact grouping (see :TRACe:EGRoup).
Thus, the time-stamp is not available for burst acquisition.
Burst acquisition can be performed for normal DCV, RMS and average ACV, normal DCI, RMS
and average ACI, and normal Ω2 measurements.
Before selecting the burst acquisition mode, configure the Model 2001 for the desired measure-
ments (such as a valid function, a manual measurement range, and a math calculation
(:CALCulate1) if desired). Also, configure the buffer for the number of readings to be stored (see
Trace subsystem).
After burst acquisition is selected, the instrument will go into the idle state (ARM indicator off).
After taking the instrument out of idle (:INITiate or :INITiate:CONTinuous ON), the pro-
grammed scan event (:see :ARM:LAYer2 SOURce) will start the storage process.
