Macros
Keypad Macros
A sequence of front panel key presses can be recorded and played as a macro. There are
10 macros which may be defined. Macro definitions are retained at power down. Macros
are saved to disk with the instrument settings.
Use [Macro Rec] ([Alt] [Pause/Cont]) to start recording a macro. Use the knob to select
which macro (0..9) will be recorded and press [Enter]. Press the desired sequence of
keys. The instrument responds to these keys while the macro is being recorded. Press
[End Rec] ([Alt] [Stop Capture]) to stop recording the macro.
To play a recorded macro, press [Play Macro] ([Alt] [Start/Reset]), choose the desired
macro with the knob and press [Enter].
To edit a recorded macro, use [System] <Edit Macro>.
Choosing From Lists
The knob is normally used to pick an entry from a list. However, knob movements are
recorded as movement relative to the starting position. This leads to ambiguity when
using the knob in a macro. Playing the macro will have different results depending upon
the starting state of the instrument. Thus, using the knob within a macro to choose a
parameter is not recommended.
To choose a parameter from a list, the numeric keys should be used instead of the knob
while recording a macro. The list choices are numbered 0 through 9. Press a number key
to make a selection and [Enter] if required. For example, to select the Hanning window,
press [Window] <Window> [2] [Enter] since Hanning is entry number 2.
If the parameter list has more than 10 choices, FFT Measurement for example, then the
knob must be used. In this case, use a numeric key entry to first pick a known selection
and then use the knob to select an entry in the list relative to it. For example, to choose
Capture1 as the FFT Measurement, press [Display Setup] <Measurement> [0] [Enter]
<Measurement> {select Capture1 with the knob} [Enter]. The first entry selects FFT1
with the [0] key regardless of the current measurement. The knob then selects a position
in the list relative to FFT1.
Menus
When recording a macro, remember that the macro is played back EXACTLY as
recorded. Thus, do not start a macro with a softkey press since the menu which is
displayed at playback may not be the one displayed when the macro was recorded.
Always start a macro with a menu key press if you want to change parameters within a
menu.
