<rmt> <RESPONSE MESSAGE TERMINATOR>
<cpd> <CHARACTER PROGRAM DATA>: a short mnemonic or string such as ON or
OFF.
<nrf> A number in any format. For example, 12, 12.00, 1.2 e 1 and 120 e-1
are all accepted as the number 12.
Any number, when received, is converted to the required precision consistent
with the use, then rounded up to obtain the value of the command.
<nr1> A number with no fractional part, i.e. an integer.
[…] Any item(s) enclosed in these brackets are optional parameters.
If more than one item is enclosed then all or none of the items are required.
The commands which begin with an asterisk (
*
) are those specified by IEEE Std. 488.2
as Common Commands. All will function when used on the RS232 interface but some
have little applicability here.
Channel Selection
Most commands act on a particular channel of the generator. The following command is
used to select the required channel. Subsequent commands will change only the specified
parameter on the selected channel.
SETUPCH <nrf> Select channel <nrf> as the destination for
subsequent commands.
The value of
<nrf> ranges from 1 to the
highest channel number in the instrument.
Frequency and Period
These commands set the frequency or period of the generator main output and are
equivalent to pressing the
FREQ key and editing that screen.
WAVFREQ <nrf> Set the waveform frequency to <nrf> Hz.
WAVPER <nrf> Set the waveform period to <nrf> sec.
CLKFREQ <nrf> Set the arbitrary sample clock freq to <nrf>
Hz.
CLKPER <nrf> Set the arbitrary sample clock period to
<nrf>
sec.
WFMCLKSRC <cpd> Set the playback clock source of the selected
waveform to
<INT> or <EXT>.
Amplitude and DC Offset
AMPL <nrf> Set the amplitude to <nrf> in the units as
specified by the
AMPUNIT command.
AMPUNIT <cpd> Set the amplitude units to <VPP>, <VRMS>
or <DBM>.
ZLOAD <cpd> Set the output load, which the generator is to
assume for amplitude and dc offset entries, to
<50>
(50Ω), <600> (600Ω) or <OPEN>.
DCOFFS <nrf> Set the dc offset to <nrf> Volts.
