In NORM byte order, the most significant byte (MSB) of each data point is
assumed first.
In SWAP byte order, the least significant byte (LSB) of each data point is
assumed first. Most computers use the “swapped” byte order.
The waveform generator represents binary data as signed 16-bit integers, which
are sent as two bytes. Therefore, each waveform data point requires 16 bits,
which must be transferred as two bytes on the waveform generator’s interfaces.
FORMat:BORDer?
Query the byte order for binary transfers in the block mode. “NORM” or “SWAP”
will be returned.
FREQuency:STARt {
ramps, from 1µHz to 10 MHz for arbitrary waveforms, from 1µHz to 25 MHz for
square, and from 1µHz to 50 MHz for sine. The default is 100 Hz. The minimum
value is 1µHz and the maximum value is 50 MHz.
FREQuency:STARt? [MINimum|MAXimum]
The start frequency in sweeps will be returned.
FREQuency:STOP {
ramps, from 1µHz to 10 MHz for arbitrary waveforms, from 1µHz to 25 MHz for
square, and from 1µHz to 50 MHz for sine. The default is 1 KHz. The minimum
value is 1µHz and the maximum value is 50 MHz.
FREQuency:STOP? [MINimum|MAXimum]
The stop frequency in sweeps will be returned.
FREQuency:CENTer {
ramps, from 1µHz to 10 MHz for arbitrary waveforms, from 1µHz to 25 MHz for
square, and from 1µHz to 50 MHz for sine. The default is 550 Hz. The minimum
value is 1µHz and the maximum value is calculated based on the frequency span
