Remote Interface Command

Use the following commands for assigning your channel conditions:

4.8 Trigger Setting

All measurement functions are almost performed in auto-trigger default mode. One may manually turn off auto triggering and/or make changes on related settings if it’s needed.

When auto-triggering is off, users are allowed to specify the voltage level at which the corresponding input channel triggers an event. When auto-triggering is on, users are allowed to specify the percentage of an input signal at which the Counter triggers an event. In addition, one may specify sensitivity level to avoid incorrect events triggered due to noise.

5353

Sensitivity at a particular frequency is the lowest amplitude signal to trigger the counter for counting. The amplifier gain and the voltage difference between the trigger hysteresis levels determine the sensitivity of the counter. Sensitivity is specified by the upper and lower levels with the trigger level fixed at the middle. The input signal must cross both the upper and lower levels in order to trigger a count as shown in Figure 4-12. If the peak-to-peak amplitude of a signal does not exceed the limits, this signal will not trigger a count as shown in Figure 4-13. Moreover, the counter also won’t do a count as the trigger level which is set below the midpoint of the signal can’t cross the limit as shown in Figure 4-14.

The MEASure? Command

Although it does not offer much flexibility, using the command :MEASure? is the simplest way to program the Counter for measurement. With the command, the Counter makes measurement according to the selected measurement function and sends the result to the output buffer.

:MEASure[:SCALar]:<function>? <parameters> [,<source_list>]

For more information about <function>, <parameters> and <source_list>, please refer to the above table.

• If users skip the parameters and the function, or use the keyword DEFault,

the default setting (parameters and function) will be used.

• Using this command automatically turns off the statistics, scale and offset

and limit testing operations.

• If the trigger level is not specified in <parameters>, then auto-triggering will

be enabled and the trigger levels will be automatically set in all functions but Voltage Peaks and Totalize on the measurement channel.

The CONFigure Command

The CONFigure command offers a little more flexibility than the command MEASure? and is usually used with the commands READ?. The universal counter sets the parameters for the requested function, but does not make measurement. Users have an option to change the configuration. To initiate the measurement, READ? Or INITiate commands can be used.

:CONFigure[:SCALar]:<function> <parameters> [,<source_list>]

For more information about <function>, <parameters> and <source_list>, please refer to the above table.

• If you skip the parameters or the function, or the source list, or use the

keyword DEFault instead, the default settings (parameters, function and source) will be used.

• Using this command automatically turns off the statistics operation, scale

and offset operation and limit testing.

• If the trigger level is not specified in <parameters>, then auto-triggering will

be enabled and the trigger levels will be automatically set in all functions but Voltage Peaks and Totalize on the measurement channel.

The READ? Command

The command READ? is often used with the command CONFigure? to have a effect similar to the command MEASure? in which the users provide required parameters, configure the counter and make measurements. The command :CONFigure? does the configuration part of the measurement, and the command :READ? does the data acquisition and post processing (if any), and puts the result in the Output queue. Use this command combination to instruct the counter to perform something between the measurement setup and data acquisition.

:READ[[:SCALar]:<function>]?

For more information about <function>, <parameters> and <source_list>, please refer to the above table.

Using the command READ? has a same effect as using the command INITiate[:IMMediate] followed by the command :FETCh?.

The Commands INITiate and FETCh?

These two commands provide the lowest level of control of measurement triggering and reading retrieval, but offer the most flexibility. After you have configured the universal counter, use the command INITiate to initiate the measurements. The results are sent to the internal memory and stored until you are ready to read them.

FETCh[[:SCALar]:<function>]?

For more information about <function>, please refer to the above table.

The command FETCh? sends the data in the universal counter’s internal memory to the output buffer where you can read them into your bus controller.

Errors are retrieved in first-in-first-out (FIFO) order. The first error returned is the first error that was stored. Use :SYST:ERR? to read errors. When user has read all errors from the queue, the error queue becomes empty and any error query will return +0, “No error”. The MODEL 1105 beeps once each time an error occurs.

Should more than 29 errors have existed, the last error stored in the queue (the most recent error) is replaced with -350, “Queue overflow”. No additional errors are saved until you remove errors from the queue.

The error queue is cleared when power is off or after a *CLS (clear status) command is executed. The *RST (reset) command does not clear the error queue.

7.2 Execution Errors

 -200 Execution error

This is the generic syntax error if the Counter cannot detect more specific errors. This

code indicates only that an Execution Error has occurred.

 -210 Trigger error

Used when the Counter cannot detect a more specific error from the :INIT, :TRIG,

or :ABOR subsystems.

 -211 Trigger ignored

Indicates that a GET or *TRG was received and recognized by the Counter but was

ignored.

 -213 Init ignored

Indicates that a request for a measurement initiation was ignored as another

measurement was in progress.

 -220 Parameter error

Indicates that a program data element related error occurred. This error is used when

the Counter cannot detect more specific errors.

 -221 Setting conflict

Indicates that a legal program data element was parsed but could not be executed

due to the current Counter state.

 -222 Data out of range

Indicates that a legal program data element was parsed but could not be executed

because the interpreted value is outside the legal range defined by the Counter.

Typically, the value is clipped to legal limit.

 -223 Too much data

Indicates that a legal program data element of block, expression, or string type was

received that contained more data than the Counter could handle due to memory or

related Counter-specific requirements.

 -224 Illegal parameter value

Used where exact value, from a list of possible values, was expected.

 -230 Data corrupt or stale

No valid data available. New measurement started but not completed.

 -240 Hardware error

Indicates that a legal program command or query could not be executed because of

a hardware problem in the Counter.

 -241 Hardware missing

Indicates that a legal program command or query could not be executed because of

9292

missing Counter hardware. For example, the Channel 3 option was not installed.

 -272 Macro execution error

Indicates that a syntactically legal macro program data sequence could not be

executed due to some error in the macro definition.

7.3 Device-Specific Errors

 -300 Device-specific error

This is the generic device-dependent error.

 -310 System error

Indicates that a system error occurred.

 -330 Self-test failed

Indicates at least one failure occurred when *TST? was executed.

 -350 Queue overflow

There is no more room in the error queue and an error occurred.

7.4 Query Errors

 -400 Query error

This is the generic query error.

 -410 Query INTERRUPTED

Indicates that a condition causing an INTERRUPTED Query error occurred. For example,

a query followed by DAB or GET before a response was completely sent.

 -420 Query UNTERMINATED

Indicates that a condition causing an UNTERMINATED Query error occurred. For

example, the Counter was addressed to talk and an incomplete program message was

received.

 -430 Query DEADLOCKED

Indicates that a condition causing a DEADLOCKED Query error occurred. For example,

both input buffer and output buffer are full and the Counter cannot continue.

 -440 Query UNTERMINATED after indefinite response

Indicates that a query was received in the same program message after a query

requesting an indefinite response ( for example, *IDN? or *OPT?) was executed.

The graph doesn’t include the effects of trigger error. To place an upper bound on the added effect

of this error term, it’s necessary to determine the frequency error from the proper graph and add a

trigger error term as the following equation:

External source and input amplifier noise might advance or postpone the trigger points that define

the start and end of a measurement. The resulting timing uncertainty is a function of the slew rate

of the signal and the amplitude of spurious noise spikes (relative to the input hysteresis band).

The (rms) trigger error relative to a single trigger point is:
