Section 3
Command:
N (fft summation method)
Syntax:
N[x]
Purpose:
The N command can be used to select the method used by the FFT
built-in processing routines to determine the peaks of the spectrum.
The default is to use a three cell summation as described in
Appendix E.
[x] can be any one of the following:
1
Disable 3-cell summation
0
Enable 3-cell summation (default).
The N command allows selecting the optimal processing methods for
determining the amplitudes of the frequency components. For signals
(and harmonics) closely lined with the FFT frequency cells, N1
should be used. This requires careful selection of the FFT size and
sampling frequency to match the input signal. For general purpose
applications, the default N) should be used.
Examples:

Appendix H: Performance Verification
Self Test
The VX4240 includes a built-in self test feature (BITE) which is executed
automatically at power-on and (more extensively) when the Self Test command
(S) is issued. Internal test routines and reference circuitry verify the CPU, RAM,
A/D converter, and the analog input amplifiers. Parameters tested include
common mode, coupling, offset, and range gain. No external test equipment is
required .
In addition to BITE, two of the front panel indicator lights display the current
status of power and the SYSFAIL* error condition. The front-panel alphanumeric display will show error codes due to a hardware failure or incorrect
programming. The error command (E), may be used at any time during operation
to determine the current state of the module.
Following the system initialization the front panel will normally display RDY
and the green PWR light will be on indicating that the self test has passed and
that the power supplies are operational. If the +5 V, ±24 V (including the derived
±15 V), –5.2 V, or –2 V power supplies fail, or if a corresponding fuse opens, the
PWR light will be off and the red FAILED light will be on (indicating that
SYSFAIL* has been asserted due to a failure).
NOTE. If you experience an error indication from the Slot 0 Resource Manager,
the VX4240-under-test, or other VXIbus module, investigate and correct the
problem before proceeding. Common items to check are logical address conflicts
(primary and secondary; see Table A–3), breaks in the VXIbus daisy chain
signals, improper seating of a module, loose GPIB cable, improperly set Slot 0
single step switch, or loose or blown fuses.
Performance Verification Tests
This procedure contains instructions for the example test equipment listed in
Table A–1. You may use instrumentation other than the recommended example if
it meets the minimum requirements listed. The order of execution has been
chosen to minimize system setup and programming requirements. Although not
essential, it is recommended that you follow the order presented, as some tests
rely on previously verified parameters.

Prerequisites
All prerequisites listed on page A–40
1. To verify the system configuration, send the TABLE command to the Slot 0
Resource Manager and confirm the responses shown in table A–5. Your
configuration may not be identical, but the responses should be similar. (If
you are using a controller other than the VX4521, use the equivalent
procedure to observe the system configuration.)

A–45
Appendix H: Performance Verification
(Observe S00000.., see Query command 3-79)
3. Verify the VX4240 VXIbus interrupt capability with the following steps:
NOTE. Make sure your Slot 0 controller and the VX4240-under-test are set to the
same interrupt level. Also, if you are using National Instruments NI-488.2
software, make sure Auto Serial Polling is disabled to prevent the SRQ from
being reset prior to a visual check.
a. Set the VX4240 to its power-on default state, enable VXIbus Request
True Backplane interrupt (due to a triggered condition), assert a trigger,
and read the result:
(Observe RFI, TRG and MC lights on)
(Observe S00011 response and VX4521 indicates S)
b. Check that the RFI light is now off, the TRG and MC lights are on, and
that the Slot 0 controller (VX4521) displays an S for an SRQ pending.
The response S00011 indicates that the Acquisition memory is full and
that Real Time data has been updated (see Query command 3-79).

Adjustment
This sequence first adjusts the DC gain and input signal path imbalances for the
0.5 V and 5.0 V ranges and then adjusts for maximum common mode rejection.
New adjustment constants are stored in non-volatile memory.
1. Connect the DC Calibrator to the VX4240 SIG IN+ and SIG IN– using equal
length coxial cables, a BNC-T, and a BNC-to-Dual Banana adaptor.
2. Set the DC Calibrator for +0.49000 VDC.
3. Set the VX4240 to auto-adjust DC gain and offset for the 0.5 V range
(Note: While the auto-adjustment is converging, the front panel will display
hexadecimal values and when complete, will display RDY):
(Observe hex values and then RDY)
4. Set the VX4240 to display the differential input voltage for the 0.5 V range,
and while observing the front panel display, adjust R1111 for the closest
reading to 0.0 (±15.0 maximum):
(Observe display and adjust R1111)

(Observe hex values and then the RDY)
8. Set the VX4240 to display the differential voltage for the 5.0 V range, and
while observing the front panel display, adjust R1514 for the closest reading
to 0.0 (± 15.0 maximum):
(Observe display and adjust R1514)
9. Repeat steps 7 and 8 until no additional adjustment is required in step 8.
DC Gain and Offset
Adjustment
This sequence auto-adjusts the DC gain and balances the differential offset for all
eight voltage ranges. New adjustment constants are stored in non-volatile
memory. While the auto-adjustment is converging, the front panel will display
changing hexadecimal values. When the command is complete, the module will
display RDY, indicating that the next range may be adjusted. If the module does
not converge for a specified range, the display will indicate an error number. The
Error command (E) may be used to read the cause of the failure. This usually
occurs if an incorrect voltage has been set up for the range being adjusted.
1. Connect the DC Calibrator to the VX4240 SIG IN+ input only, using a
coaxial cable and a BNC-to-Dual Banana adaptor.
2. As specified in Table A–18, adjust the eight voltage ranges by setting the DC
Calibrator and sending the auto-adjustment command for each calibrator
setting according to Table A–18.
3. When RDY appears on the display after each auto-adjustment command,
reverse the polarity of the calibrator voltage and read the negative voltage
using the following commands:
ibwrt “R;CT10002;VD#;TF\n”
(substitute the # with the voltage range 0.5, 1, 2...etc.)
ibwrt “AA10000/0\n”
ibrd = measured negative voltage
4. Calculate the new calibration voltage with the following equation:
New cal. voltage = [-(cal.voltage) - (measured negative voltage)]/2 + cal.

5. Set the calibrator to the new calibration voltage and send the autoadjustment
command according to Table A–18.
Example: To set DC gain and offset in the 2V range, do the following:
1. Set the DC calibrator to +1.96V.
2. Send the command “ks2\n” and wait for RDY to appear in the display.
3. Set the DC calibrator to –1.96V.
4. Send the command “R;CT10002;VD2;TF\n”.
5. Send the command “AA10000/0\n”.
6. Read the VX4240 and get the measured negative voltage.
7. Use the voltage measured in step 6 and the following equation to calculate
the new calibration voltage.
Example:
1.964695 = [–1.96 – (–1.96939)] /2 + 1.96
8. Set the DC calibrator to +1.964695V.
9. Send the command “ks2\n” and wait for RDY to appear on the display and
proceed to the next range.

Appendix J: Binary Transfer
If you are using a National Instruments GPIB-VXI/C Slot 0 module and are
planning on using the binary transfer capabilities of the modules above, you will
need to load a CI (Code Instrument) into the GPIB-VXI/C Slot 0.
NOTE. The GPIB-VXI/C Slot0 has an internal buffer that holds the data to be
read out. The buffer will automatically take a reading from the module upon a
GPIB read. The buffer will read the module until it receives an END BIT (bit 8
set in the response to a byte request command). The Tektronix products above do
not set bit 8 on readback, thus the GPIB-VXI/C Slot0 will fill its buffer with data
(approximately 450 Kbytes). If you only request 1 Kbytes of data over GPIB
there still will be 449 Kbytes of data in the buffer. This data will remain in the
buffer until read out. If you should request data from another module the data
that you will receive back will be from the data that is left over in the buffer
(449 Kbytes).
National Instruments has developed a code instrument that will read the exact
number of bytes that was requested over the GPIB bus from the module. The
code instrument will not read more data then requested and will have no leftover
data in the buffer. Refer to the National Instruments GPIB-VXI/C manual for
information on code instruments.

representative.

If you are using a National Instruments GPIB-VXI/C Slot 0 module, you may
have trouble attaining an IEEE-488 address for the VX4240. When the system is
powered on the GPIB-VXI/C Slot 0 resource manager does not assign a GPIB
address because the RESMAN delay is too short to allow the VX4240 to
perform its self test. To correct the problem change the RESMAN delay when
you power on to set the GPIB-VXI/C Slot 0 nonvolatile memory.
Perform the following steps:
1. Connect an RS-232 cable to the GPIB-VXI/C Slot 0 serial port and the
opposite end to a terminal. (Refer to the National Instruments User manual.)
2. Power on the GPIB-VXI/C Slot 0. The following information should appear
on the screen.

3. Type in CONF and press enter. The following information should appear on
the screen.
