44.2 REF SAVE

Pressing and holding opens the SAVE menu and displays
the options “All displayed” and below that item a line in
which one of the 3 reference memories (REF1, REF2,
REF3) can be selected to store the content from one of 5
likewise selectable signal sources (CH1, CH2, MAT1,
MAT2, MAT3).

If “All displayed” is chosen and “Set” has been pressed,
all signals are stored into the reference memories that
were displayed before calling SAVE. The following
assignment is made automatically: If CH1 was visible it is
stored into REF1, CH2 ..... REF2, MAT1 or 2 or 3 ...... REF3.
This means that if e.g. mono channel mode CH2 is saved
on condition “All displayed” only the memory content of
REF2 is overwritten and the contents of REF1 and REF3
stay unchanged.

The line below “All displayed” follows the pattern: Target
= Source. REF1, REF2 or REF3 can be chosen as target in
which a signal can be stored. CH1, CH2, MAT1, MAT2 or
MAT3 can serve as sources.

[45] DISPLAY – PRINT

  - Pushbutton with double function.

STORAGE MODE ONLY

45.1 DISPLAY

Briefly pressing the pushbutton opens the DISPLAY menu.

Under item 

“DOT JOIN”

 you can choose whether the

channels and/or the reference and mathematic signals are
displayed with [x] or without [ ] a linear connection from
one sampling point to the next.

The signal source information can be activated or
deactivated in the same way. If activated the information
displayed has the meaning: Y1 = channel 1, Y2 = channel
2, R1 = REF1, R2 = REF2, R3 = REF3, M1 = MAT1, M2 =
MAT2 and M3 = MAT3.

45.2 PRINT

Pressing and holding the pushbutton starts a documen-
tation (hardcopy) if the following preconditions are met:

1. The oscilloscope must be connected to the external

HAMEG

     interface     

HO79-6

.

2. The software version installed in     

HO79-6

     should not be

< V3.00.

The device used for documentation (e.g. printer, plotter)
must be connected with one of the HO79-6 

 HO79-6 

 HO79-6 

 HO79-6 

 HO79-6 ports. The

documentation includes the signal display, the graticule,
the measurement parameters and additional information
such as oscilloscope type and HO79-6 

 HO79-6 

 HO79-6 

 HO79-6 

 HO79-6 software version.

The     

PRINT

     function emulates the     

HO79-6  ”START”

pushbutton, which may not be accessible (e.g. rack mount).

For further information please note  the HO79-6 manual.

E: MAIN MENU

The instrument software contains several menus. The
following menus, submenus and menu items are available:

1. ADJUSTMENT

     contains:

1.1     AUTO ADJUSTMENT     with the items

1.1.1 SWEEP START POSITION

STORAGE MODE ONLY

1. RESET in combination with SINGLE mode (one time
event capture):

If the readout indicates “sgl” and the RESET – SINGLE
pushbutton is pressed briefly, the 

RES 

- LED is lit. Whether

the RES LED just flashes or lit for a longer time depends
on,

a) if a signal is present that triggers immediately,
b) which time coefficient is chosen,
c) the pre or post trigger setting.

As soon as the RES LED lights, the signal capture starts.

Attention!
If time coefficients between 100s/div and 50ms/div
are present the signal acquisition becomes visible at
once as a ROLL display, but the signal acquisition has
nothing to do with ROLL mode.

In combination with pre trigger, the pre history must have
been recorded until a trigger event can effect the trigger
unit. After triggerring and completed recording the RES
LED extinguishes.

Signals captured in DUAL channel operation mode can
also be displayed in XY mode after they have been saved
by “hld” (HOLD).

2. RESET in combination with “env” (ENVELOPE) or “avm”
(AVERAGE) mode.

The signal display is reset by briefly pressing the RESET –
SINGLE pushbutton if “env” or “avm” signal display mode
is present, causing a new signal acquisition start.

STORAGE MODE ONLY

Capturing single events can also be carried out in analog
Yt 

Yt 

Yt 

Yt 

Yt (time base) mode (e.g. photographing).
Briefly pressing the     

SINGLE

     pushbutton activates the 

RES-

LED 

in “sgl”     

(SINGLE)

     mode. The next trigger event then

unblanks the beam and causes one time base sweep.

Only in chopped 

DUAL

 mode can both channels be

displayed during one time base sweep.

[44] REFERENCE – REF SAVE

  -  Pushbutton with double

         function.

STORAGE MODE ONLY

The instrument has three non volatile reference memories.

44.1 REFERENCE

Briefly pressing opens the SHOW menu. The operation is
described under “

B: Menu Display and Operation

”.

One of the reference memories REF1, REF2 or REF3 can be
chosen to be displayed after leaving the menu. To recall the
signal and the original instrument settings, the [x] must be set.

If “None” is selected no reference signal will be displayed.
Consequently call REFERENCE and select “None” to
switch the reference display off.

After selection press “Set” to activate the last setting and
to leave the menu.
