Front-Panel Overview
Control
Save Key
The Save key allows you to save the current front-panel setup to one of the
nine volatile setup memories. When you press the Save key, the message
"select digit 1-9 for setup save" is displayed. Simply use the keypad to select
one of the nine waveform memories. After you select a setup memory, the
message “setup #7 saved" is displayed. The oscilloscope uses memory 0 to
store the current configuration before executing an autoscale, recall, or
ECL/TTL preset.
Recali Key
The Recall key has three functions.
First, you can use the Recall key to retrieve a front-panel setup from one of
the nine setup memories (providing that you previously saved a setup to that
memory). If a setup was previously saved to that memory, the scope is
immediately configured to match that setup, and the message “setup #7
recalled" is displayed. If a setup is not stored in that memory, the
configuration of scope is left alone, and the message "bad data no recall done"
is displayed.
Second, you can use the Recall key to retrieve the previous configuration by
pressing Recall 0.
Third, youc:..’ use the Recall key to set the oscilloscope to a default
operating condition by pressing Recall clr (clear key on the keypad). The
default settings are shown in table 2-1.
