Power Switch
The front panel switch is used to switch on and off the instrument.
When the front panel switch is off, the instrument is in standby mode. The
instrument is disconnected from the AC line power only by disconnecting
the power cord.
USB
The Front Panel contains a USB host connector. It is intended to connect
USB drives to store instrument states and waveforms on an external
memory.
Menu Softkeys
The five keys below the main display screen are called softkeys (softwarecontrolled keys). The current function of each softkey is indicated in the
corresponding box on the display.
Some softkeys hold additional symbols to indicate that they provide
extended functionality.
Yellow Triangles: These are visible on the five softkeys on the
Front Panel. The yellow triangles indicate that there are more choices
further, and keep pressing to view the available options.
White Rectangles: Indicate that by pressing them, you can
enter into another screen.
The following examples explain the above-mentioned points:
Pressing this softkey will toggle between
Frequency and Period representation.

Front-Panel Menu Operation
Pressing the Cancel key cancels the selection/input and helps you exit out
of a screen. But the functionality of exiting out of a screen is limited to a
few screens, like selecting an Arbitrary waveform.
The 81150A / 81160A consists of two channels and operates in two
different modes of operation:
Coupling off: The two channels operate entirely independent. Frequency
generation for both channels is based on same clock reference.
Coupling on: The frequency, trigger mode, waveform type and advanced
mode are identical for both channels. The delay between the channels is
specified.
A modulation input (for AM, FM, PM, FSK, PWM) for each channel is
provided on the back-panel. In the two channel version each channel can
modulate the other channel.
Refer to the Appendix for a list of all coupled parameters.
Press the Graph key to view a graphical representation of the waveform.
Press it again to exit from that mode.
Not every screen has a graphical representation, e.g. like the Trigger Mode
Screen.

Appendix
Inputs/Outputs
The major inputs and outputs of the instrument are available at the front
panel:
The external input (EXTERNAL IN) can be used to connect an
external arming source (triggered or gated modes).
The trigger signal (TRIGGER OUT) marks the start of the pulse period
or of parts of a pattern (see Mode/Trigger Screen.). You can set the
output levels according to the used technology (TTL and ECL) or
enter test-specific values. Trigger Out is available as a physical BNC
connector at the 81150A. For the 81160A, a ‘Logical Trigger Signal’ is
generated for channel 1 and channel 2 internally and is routed to the
physical BNC connector Sync Out A and/or Sync Out B using a
configurable switch matrix.
The strobe signal (STROBE OUT) marks beginning and end of a burst
in Burst mode. Strobe Out is available as a physical BNC connector
at the 81150A. For the 81160A, a ‘Logical Strobe Signal’ is generated
for channel one and channel 2 internally and is routed to the physical
BNC connector Sync Out A and/or Sync Out B using a configurable
switch matrix.
81160A only: The sync signal (SYNC OUT) outputs the ‘Logical
Trigger Signal’ and/or the ‘Logical Strobe Signal’ at the front panel
BNC connector. The instrument offers full flexibility how ‘Logical
Trigger Signal’ and/or ‘Logical Strobe Signal’ is routed to Sync Out A
and/or Sync Out B.
The OUTPUT connectors provide the signal output (normal and
inverted) and the indicators show the current state of the output (on
or off).
Special Function
Keys
The instrument provides the following special function keys:

The following sections provide more details on the modulation types.
The Store/Recall key can be used to store to/recall from 1 to 4 individual
settings in the instrument memory. In the internal memory location 0 there
is a default setting stored.
The Utility key enables you to enable/disable DC mode, change the Output
Setup, and also contains information about the I/O Interfaces and the
system settings of the 81150A / 81160A.
The Help key provides access to the instrument’s integrated help or in
warning or error state, access to Warning/Error Report screen.

Front-Panel Menu Operation
Entering/modifying
numbers
You can enter numbers or modify the displayed number from the front-panel
using one of the following two methods:
Rotary Knob + Arrow Keys
Numeric keypad + softkeys
For selecting units
Use the numeric keypad and menu softkeys to select the units.
The left/right arrows below the Rotary Knob are used to move left
and right to select the digit to be modified on a given screen.
When setting the cursor to the ‘exponent field’ the exponent can be
changed via the Rotary Knob (only if the resulting number does fall
within the allowed range)
The cursor position is remembered when the cursor is placed on the
leftmost digit and the value is decreased from 1 to 0. In this case the
cursor changes it’s color to green for some seconds and the cursor
position will be set back to the previous one when incrementing the
value again. For example, select the frequency to be edited and set
the cursor to the leftmost digit and then decrement the value by
turning the Rotary Knob counter clockwise. The cursor will move one
digit to the right when the digit would go from 1 to 0 and changes it’s
color to green. When incrementing while the cursor is green, it will
jump back to the initial digit when crossing the 0 to 1 border.
The left arrow key can be used to delete the digit left to the input
cursor when entering values with the numeric keypad.
