Loading a memory location
As an alternative to the parameter field (<mem_paras>) a <Definite Length Block> can be
transferred with binary data.
Parameters:
<name> MEM0 to MEM999 | RX | CURRENT | NEXT
<mem_paras> <F>, <THR>, <DEM>, <BW>, <ANT>, <ATT>, <ATTA>,
<SQUC>, <AFC>,<ACT>
<F> frequency (see SENS:FREQ:CW)
<THR> squelch threshold (see OUTP:SQU:THR)
<DEM> type of demodulation (see SENS:DEM)
<BW> bandwidth (see SENS:BWID)
<ANT> antenna number (see ROUT:SEL)
<ATT> attenuator (see INP:ATT:STAT)
<ATTA> attenuator auto (see INP:ATT:AUTO)
<SQUC> squelch function (see OUTP:SQU:STAT)
<AFC> AFC function (see (SENS:FREQ:CW:AFC)
<ACT> setting/resetting the memory to scan (ON/OFF or
1/0)
<packed_struct> binary data set as <Definite Length Block> with the
following structure:
Frequency in Hz 4 bytes = unsigned long integer
Squelch threshold in 1/10 dBuV 2 bytes = signed integer
Demodulation type 2 bytes = meaning:
0 = FM, 1 = AM, 2 = PULSe, 3 = CW, 4 = USB, 5 = LSB, 6 =
IQ
Bandwidth 2 bytes = meaning:
0 = 0.15 kHz, 1 = 0.3 kHz, 2 = 0.6 kHz, 3 = 1.5 kHz,
4 = 2.4 kHz, 5 = 6 kHz, 6 = 9 kHz, 7 = 15 kHz, 8 = 30 kHz,
9 = 50 kHz, 10 = 120 kHz, 11 = 150 kHz,
Antenna number 1 byte = unsigned character 0 to 99
Attenuator 1 byte = unsigned character (1 = on / 0 = off)
Attenuator auto 1 byte = unsigned character (1 = on / 0 = off)
Squelch function 1 byte = unsigned character (1 = on / 0 = off)
AFC function 1 byte = unsigned character (1 = on / 0 = off)
Set/Reset memory 1 byte = unsigned character (1 = set / 0 = reset)
--------------------------------------------------------------------------
Total number of bytes = 16
Notes:
• When loading the receiver data set (RX) the parameter <ACT> is ignored. It must, however, be
specified.
• When loading with <packed_struct> the byte order within the 2- and 4-byte elements is
determined by the setting command FORMat:BORDer.
*RST state:
The contents of the memory locations is kept after *RST.
