... Glossary 19 Agilent 34410A/34411A Digit High-Performance 2 Multimeters Application Note Introduction The Agilent 34410A and 34411A are the latest generation digit multimeters from 2 Agilent Technologies. The 34410A and 34411A are general-purpose DMMs that give excellent price/ performance in a wide range of applications. Each DMM builds ...

... The 34410A and 34411A are backward compatible with the Agilent 34401A multimeter and support a 34401A emulation mode. You will find a detailed comparison of the 34401A with the new 34410A/ 34411A DMMs in Application Note 5989-4038EN, “Replacing the Agilent 34401A with the New Agilent 34410A and 34411A High-Performance Digital Multimeters.” ...

... If you are considering replacing the 34401A in your test system, all you need put the 34410A or 34411A in emulation mode using the “SYSTem:LANGuage 34401A” command. You do not have to rewrite your tests – except to compensate for a much faster instrument and higher-resolution measure- ments ...

... DMMs. The next section, “Understanding Fast Measurements,” will show you how to configure your DMM for these measurements. Precision measurements with high NMR The 34410A and 34411A use a special aperture-shaping algorithm to increase normal mode rejection (NMR) of power-line-related noise in DC measurements increasing and decreasing series of weighted averages of multiple measurements ...

... Substantial improvements in accuracy are attained using this technique. The 34410A and 34411A DMMs can actually perform much better than their 0.5% specifications. In lab testing on a high-accuracy capacitance standard, these DMMs achieved a performance level on the order of 0 ...

... DCV measurement. In that case, the ripple may retain the same peak-to-peak voltage. When the primary measurement fails, more information about the signal is required. The 34411A DMM provides wave- form capture readings/s that can sample the signal to provide additional diagnostic information. ...

... This is a relatively simple mea- surement to make for a DMM that has analog level triggering. No external TTL-pulse is needed to start the measurement. The 34411A is set to trigger at some point on the rising edge of the pulse (a percent of range). A trigger delay can be used to make sure the measurement starts on the “ ...

... DMM. If the DMM does not have effective input protection, the input circuitry can eventually fail after continued abuse. The 34410A and 34411A use a direct sampling technique to make AC RMS measurements. Relative to analog RMS calcu- lations, the direct sampling technique offers four primary ...

... The frequency content of these signals is relatively low, often less than 8 kHz. For example, a typical accelerometer will have a bandwidth of 2.5 kHz. The 34411A provides waveform capture for these types of signals using the following capabilities: • 50-kHz sample rate at 4.5 digits using a low-jitter sample timer • ...

... An external trigger event can start a single measurement or a burst of measurements spaced by the sample timer. Figure 5 illustrates the concept of a separate trigger delay and sample intervals. Sample intervals can be as low at 100 µs for the 34410A and 20 µs for the 34411A. ...

... The 34410A and 34411A use hardware coupling to connect external trigger inputs to the measurement engine. Trigger latency or jitter is less than 1 µs, so multiple 34411A DMMs running samples/s can begin sampling at virtually the same time. With each 34411A’s reading storage at 1 million readings seconds of data can be captured in parallel ...

... DMM to scan channels with the 34980A switch/measure unit. 12 The 34410A and 34411A use a fast auto-ranging technique that makes scanning a wide variety of signal levels virtually as fast as most switches can scan. Voltmeter complete and external trigger levels can be ...

... Frequency 450 90 10 Period 450 For the 34411A, note that 50 k readings/s is specified at 4.5 digits for DCV, but it is only 3 k readings/s with DCI. A speed reduction is also recommended and occurs with resistance measurements. This does not limit measuring current or resistance readings/s. ...

... Aperture is the time the A-to-D spends integrating the applied signal. The minimum DC apertures for the 34410A and 34411A are 100 µs and 20 µs, respectively. Aperture resolu- tion is 20 µs; therefore, the highest sample rate for the 34411A readings/s – ...
Page 15
... The aperture setting is set to MIN. For the 34410A, this would be 100 µs. For the 34411A, 20 µs is the MIN. The same commands can be used for DCI, ohms, or temperature – but you have to change the VOLT to CURR, RES, FRES, or TEMP. Autozero cannot be turned off when making four-wire ohms measurements ...

... How to set up various triggering scenarios The 34410A and 34411A have two triggering models. The models are illustrated in Figure 10. When you use the SCPI com- mands shown in the previous section, the count and delay pacing model is implied. If the trigger delay is zero, the ...

... The Advantages of a Built-In Web Server The 34410A and 34411A have a built-in Web server that provides a very powerful configuration, diagnosis, and programming tool. All you need is a LAN connection, Web browser, and the DMM’s IP address. If your computer can access eBay.com, you can access a 34410A/11A from anywhere ...
