Getting Started Manual
Press the soft key at the bottom right, adjacent to
the word period.
The display should look like this:
STANDARD PERIOD
80.00000 us
freq
The solid diamond is now against the word
indicating that any new keypad entry or any change made
using the rotary control will apply to the period.
The word in the display heading indicates
STANDARD
that the instrument is set up to generate one of the
standard waveforms. You can choose the waveform you
wish to generate.
Press the key
STD
The display should look like this:
STANDARD WAVEFORMS
sine

is the default setting. You can explore the full list
sine
of standard waveforms using the cursor keys or the rotary
control.
The instrument can also generate arbitrary waveforms
which are specified as a series of values from -2047 to
+2047 (corresponding to a peak to peak amplitude range
of 20 V) along a timebase of up to 65,536 points. These
are stored internally in channel memory and/or in backup
memory, and can be edited from the front panel or on a
PC using suitable software and an RS232 or GPIB
instrument interface.
Arbitrary waveforms are discussed later in this Getting
Started Manual.
For this part of the exercise we will concentrate on the
standard waveforms. At this point we have set up a sine
wave at 12.5 kHz. The amplitude of the signal at the
output socket is controlled in the same manner as the
frequency or period:
Press the key
AMPL
The display should look like this, indicating that the output
amplitude is 2 V p-p into an open circuit ( hiZ ):
