Computer Configurations
This section contains performance and functional information on the
computer configurations that can be used with register-based programming.
Throughput Speed
Throughput speed is based on the amount of command parsing and whether
the registers are accessed from the VXI backplane or from the HP-IB. The
computer configurations which allow faster throughput relative to each
other are summarized below:
1. HP E1480A V/360 Controller with
READIO
and
WRITEIO
(register access is from VXI backplane).
2. E1300/01 IBASIC absolute addressing with
READIO
and
WRITEIO
(register access is from VXI backplane).
3. E1300/01 IBASIC select code 8 with
READIO
and
WRITEIO
(register access is from VXI backplane).
4. External Computer using
DIAG:PEEK?
and
DIAG:POKE
(register access is over HP-IB).
5. External Computer using
VXI:READ?
and
VXI:WRITE
(register access is over HP-IB).
Embedded
Computer
Programming
(C-Size Systems)
If the E1340A AFG is part of a C-Size VXI system, the fastest throughput is
achieved using an embedded computer such as the HP E1480 V/360. The
embedded computer allows you to access the registers from the VXIbus
backplane, and since READIO and WRITEIO are used, there is no parsing
of SCPI command headers.
IBASIC
Programming
When the E1340A AFG is programmed using the E1300/E1301
Mainframe’s Instrument BASIC (IBASIC), two methods of accessing the
registers are through absolute addressing or using select code 8.
Absolute Addressing and Select Code 8
Absolute addressing is faster than select code 8 since the complete register
address (including the A16 starting location 1FC000
16
) is specified. When
select code 8 is used, the IBASIC processor must calculate the complete
register address based on the logical address specified (Table C-1).
