Programming the Agilent 16522A
LABel
LABel
Command/Query
The LABel command inserts a new label or modifies the contents of an
existing label. If more than 126 labels are specified, and an attempt is made
to insert another new label, the last label (bottom label) will be modified.
Only 16 labels may be inserted or modified at a time. If more than 16 labels
are specified per command, you will receive an error message.
Pattern generator channels can be assigned to only one label at a time. If
duplicate assignments are made, the last channel assignments take
precedence.
The second parameter sets the channel polarity. If the polarity is not
specified, the last polarity assignment is used. The last parameters assign the
active channels for each pod.
Each assignment parameter is a binary encoding of the channel assignments
of the pod. The pods are numbered in the same order as they appear in the
format menu, with zero representing the left-most pod (pod 5) of the
top-most card in the pattern generator module. A "1" in a bit position means
that the associated channel in that pod is included in the label. A "0" in a bit
position excludes the channel from the label. The minimum value for any pod
specification is 0, the maximum value for all pods is 255. A value of 255
includes all channels of a pod assignment. The query must specify a label
name and returns the current pod assignments and channel polarity for that
label. A maximum of 32 bits can be assigned to a label.
In half channel mode, only the four least significant bits of pod five are used.
Pods two and four are not used. Pods one and three use all eight bits. When
channel assignments are made in half channel mode, values are required for
three pods (1, 3, 5) per card.
