HP 3326A Operating And Reference Manual page 61

Memory register 0 contains the last operating state prior to removing power. The last
operating state established prior to removing power is restored by pressing the RECALL
key followed by the digit 0.
Through the use of the internal SAVE switch, the setup state stored in register 0 can
be selected as the turn on state. Setting of internal switches must be done by qualified
service personnel. The location and settings of the SAVE switch are described in the
HP 3326A Service Manual.
Memory Clear
Applying power to the HP 3326A with the blue SHIFT key pressed replaces the con-
tents of all nonvolatile memory registers with the INSTR PRESET state. All saved oper-
ating states and discrete frequency sweep elements are replaced with the INSTR
PRESET state.
Recall Discrete
The RCL DISCRETE (ReCaLI DISCRETE) key followed by a discrete frequency sweep
element number replaces the channel A and B frequency values and time value w ~ t h
the values stored for the discrete frequency sweep element. The RCL DISCRETE key
is ava~lable by pressing the blue SHIFT key prlor to pressing the RECALL key. Valid
discrete frequency sweep elements numbers range from 00 to 62 Recalling a null dis-
crete frequency sweep element displays the message "Error 20 RNGE" (RaNGE).
HP-IB Example:
Save Discrete
The SAVE DISCRETE key followed by a discrete frequency sweep element number stores
the current channel A and B frequency values and dwell time value in nonvolatile
memory. The SAVE DISCRETE key is available by pressing the blue SHIFT key prior
to pressing the SAVE key. Valid discrete frequency sweep element numbers range from
00 to 62. When initially entering discrete frequency sweep elements, the element num-
bers must start with 00 and be sequential. Existing discrete frequency elements may
a
be recalled, edited, and replaced in any order. Storing a discrete frequency sweep ele-
ment with a nonsequential number, or using a number greater than 62 displays the mes-
sage "Error 23 RNGE" (RaNGE). The message "Error 11 7 DSWP" (Discrete frequency
SWeeP) is displayed if a discrete frequency element is entered after the mode is
changed.
