Using The Instrument 3-25
The query:
SMEMory:MODE?
queries the shared memory mode and returns READ or WRITE.
The command:.
SMEMory:STATe {OFF | ON}
places the Model 3152 in the shared memory state when ON is
selected. After this, the instrument cannot accept normal
commands. Data must be sent to the synthesizer using shared
memory access. Normal command mode is resumed when the
SMEMory:STATe is changed to OFF.
The query:
SMEMory:STATe?
queries the shared memory state and returns "0" (OFF) or "1" (ON).
The following sequence should be used for shared memory
transfers.
1.
Slot 0 sends commands:
TRAC:DEF (n),(m)
(Shared Memory write only)
TRAC:SEL <n>
SMEM:MODE {READ
*
WRITE}
SMEM:STATE ON
2.
Slot 0 repeatedly sends:
*OPC?
When response is 1, shared memory transfers may start.
3.
Slot 0 sends command:
SMEM:STATE OFF
once data transfer is complete.
The *OPC? Response is set to 1 when the Model 3152 has
transferred memory access from the internal CPU to shared
memory. This typically takes a few milliseconds.
Sequence
Sequenced waveforms are a means of adding more capability to
the synthesizer. The Model 3152 can link 4096 segments and loop
on each segment up to 10
6
times.
