The Model N4865A is designed to interface with and control Agilent DSO/

MSO7000 Series and DSO/MSO9000 Series oscilloscopes. The N4865A

has two ways to connect to an oscilloscope after power turn-on and selftest.

handling GPIB commands and device messages and should only be used with

IEEE-488.2 compatible GPIB Controllers. GPIB commands are converted to

VXI-11.3 equivalents and transmitted to the companion oscilloscope. Device

The N4865A can accept reverse channel Service Requests and will assert SRQ

The N4865A's operation and network settings are completely programmable

by commands from its Ethernet interface, eliminating the need to open the unit

to change or verify a function setting. The setup parameters can be changed

ICS's N4865A Interface is packaged in ICS's small metal Minibox™ case which

provides proven EMI/RFI protection and rack mounting capability. Rear panel

RJ-45 and GPIB connectors provide access to the network and GPIB bus. Front

panel LEDs provide visual network and GPIB bus status and diagnostic help

The following speciﬁ cations apply to all N4865A models. Options for your

unit may be found by comparing the list below to those listed on the Ethernet

The N4865A's GPIB Bus drivers incorporate powerup/down protection to

prevent sending invalid data to the bus. GPIB fanout is up to 14 devices.

N4865A is addressed to talk, it sends a

Large Listen messages are handled by holding off the GPIB bus while a buffer

N4865A links with a LAN oscilloscope and becomes ready to transmit GPIB

the oscilloscope, it will attempt to reconnect to the oscilloscope.

3.2.2 GPIB Operation

The N4865A only operates correctly with an IEEE-488.2 compatible GPIB

EOI asserted on the last character as the N4865A does not check for message

terminators. The N4865A will assert EOI when it outputs the last character in

the response received from the LAN oscilloscope if the END bit was asserted

When the N4865A receives a terminated device message from the GPIB bus

the N4865A sends the data to the companion oscilloscope with the

device_write

RPC. The N4865A holds the GPIB bus while transmitting the data to the com-

panion oscilloscope. In the case of large messages, the N4865A sends the data

to the companion oscilloscope when its GPIB listen buffer becomes full. When

the ﬁ rst buffer load of data has been sent to the companion oscilloscope, the

N4865A accepts the next buffer worth of data. The process repeats with the

N4865A handling a buffer worth of data at a time until the N4865A receives

the last portion of the data with EOI asserted on the last byte. Unterminated

response data from the companion oscilloscope that is terminated with END

buffer, the N4865A outputs the ﬁ rst buffer of data to the GPIB bus and sends

device_read

RPC to the oscilloscope to read the next buffer's

END asserted. If the companion oscilloscope returns a zero length response,

the N4865A will not have any data for the GPIB bus and the GPIB read opera-

tion will timeout.

When the N4865A is addressed to talk and has received a response packet with

END asserted, it will not fetch additional data from the companion oscilloscope

until it has been addressed to listen and sent a device message, a GPIB Device

Trigger, a GPIB Device Clear command or an Interface Clear.

When the N4865A is transistioned to the Listen Active State from the Talk

Active State, it discards any data in the GPIB talk buffer. Similarly, when the

N4865A is transistioned to the Talk Active State from the Listen Active State,

If the N4865A receives a Service Request from the oscilloscope over the

Reverse Interrupt channel, the N4865A will query the oscilloscope's Status

The SRQ line will be deasserted and the SRQ LED will be turned off. Future

3.3 PROGRAMMING GUIDELINES

The N4865A can be used successfully to operate a LAN oscilloscope with

to compensate for delays in converting the commands and transmitting them

The following multiple sequences should be avoided:

3.3.1 Multiple Triggers

488.1 GET.

3.3.2 Multiple Device Clears

the oscilloscope(s) to clear their buffers and output lines. Many oscilloscopes

3.3.3 Multiple Serial Polls

Multiple high speed Serial Polls will return the same value. The N4865A's

Request and before asserting the SRQ signal and periodically thereafter at a 3

rial Poll updates are inhibited while the N4865A is in the listen addressed state

Trigger, after a Device Clear command or after an Interface Clear.

3.3.4 Message Terminators

requires that all Device data messages sent to it be terminated with EOI as-

terminated with both a linefeed character and EOI asserted. (The IEEE-488.2

NL terminator)

The N4865A's GPIB responses are terminated with EOI asserted on the last

byte. Any terminating character is supplied by the companion oscilloscope as

part of its response message.

3.3.5 Transferring Large Files

The N4865A transfers large data ﬁ les in blocks of one Talk buffer or one Listen

buffer worth of data at a time. These buffers are a maximum of 1,024 bytes.

Users should set their program to read data in blocks that are multiples of 1,024

bytes for best performance. The user's program should not untalk or unlisten

the N4865A in the middle of transferring large data ﬁ les. Setting readdress

time. Timeouts should be set for 1 second per kbyte of data transfer.

3.3.6 Linkage Lost

When the N4865A links to a oscilloscope, it turns the RDY LED solid on after

RPC. The N4865A only knows the

RPCs. There is nothing to alert the N4865A to the oscilloscope being turned

RPCs depends upon the Test Application. If the Test Application is quiescent

rate.

When the N4865A does not receive a valid RPC response, it turns off the RDY

LED and attempts to relink to the oscilloscope. If it is successful, the N4865A

RPC should be considered lost. The user will have to consider this in his

program.

Figure 4-1 shows a block diagram of the N4865A’s internal logic. Most of the

major logic elements center around the 16-bit data bus from the ARM7 Proces-

The FLASH chip stores the program code and the conﬁ guration parameters.

At power turn-on time, the ARM7 processor loads the program code from the

FLASH into the RAM chip. The program is then run out of the RAM chip.

At power turn-on, the processor clears the LEDs, does a brief check of the

LEDs would blink the appropriate error code. New units default to using the

program stored in the program0 space. Units that have been updated in the

The IEEE 488.2 Standard was established in 1987 to standardize message

protocols, status reporting and deﬁ ne a set of common commands for use

Semicolons are used to separate messages.

Colons are used to separate command words.

Commas are used to separate data ﬁ elds.

With IEEE 488.2, status reporting was enhanced from the simple serial

poll response byte in IEEE 488.1 to the multiple register concept shown in

Figure A-3. The IEEE 488.2 Standard standardized the bit assignments in

the Status Byte Register, added eight more bits of information in the Event

registers that can control the generation of their summary reporting bits and

ultimately SRQ generation. Each 488.2 device must implement a Status

Differences From IEEE 488.1

The user who is familiar with the older 488.1 devices should take the fol-

bit in response to a *STB? query. The MSS bit is cleared when the condi-

tion is cleared.

488.2 restricts the Device Clear to only clearing the device's buffers and

pending operations. It does not clear the Status Reporting Structure or the

488.2 commands are really special data messages and are executed by the

0. A *PSC command of 1 causes zeros to be loaded into the enable registers
