Introduction and Specifications 1
Introduction
Introduction
The DMM4040 and 4050 are 6-1/2 digit, dual-display multimeters designed for bench-top, field service, and system applications. Their full complement of measurement functions plus its RS-232, IEEE 488, and Ethernet Remote Interfaces makes these multimeters ideal candidates for precision manual measurements and use in automated systems. For portability, these multimeters include a carrying handle that also serves as a bail for bench top operation.
There are a few additional features in the DMM4050 that are not present in the DMM4040. These features will be identified with the annotation of “4050 Only” by each feature that is found only in that model. Separate specification tables are also used to clarify the differences between these two models.
The following is a list of some of the features and functions:
•Bright, large-digit, wide-viewing-angle display
•Dual display for displaying two properties of an input signal (e.g., ac voltage in one display and frequency in the other).
•Remote operation via IEEE 488, RS-232, and Ethernet interface.
•Trigger in and measurement-complete out
•Front panel USB port for optional memory
•6-1/2 digit resolution
•Half-rack width
•True rms ac
•2 and 4-wire resistance measurements
•Extended 10 Ω and 1 GΩ ranges
•Frequency measurements to 1 MHz
•Capacitance measurements (4050 only)
•Temperature measurement (4050 only)
•10 A current capability
•Decibels (dB and dBm) with variable reference impedance and audio power measurement capability
•Input terminals on both front and rear panels of the meter
•Closed-case calibration (no internal calibration adjustments)
This technical reference manual focuses on performance verification and calibration of the Tektronix DMM4040 and 4050 Digital Multimeters (hereafter referred to as the Meter).

Electrical Specifications
Accuracy specifications are valid for 6½ digit resolution mode after at least a 1-hour warm-up with Auto Zero enabled.
24-hour specifications are relative to calibration standards and assume a controlled electromagnetic environment per EN 61326-1:2000-11

Autozero Off Operation........................................... |
Following instrument warm-up at calibration temperature ±1 °C and |
|
less than 10 minutes, add error: 0.0002 % range additional error |
|
+5 µV. |
Analog Filter............................................................ |
When using the analog filter, specifications are relative to within one |
|
hour of using the ZERO function for that range and NPLC setting. |
DC Ratio ................................................................. |
Accuracy is +/- (Input accuracy + Reference accuracy), where Input |
|
accuracy = DC Voltage accuracy for the HI to LO Input (in ppm of the |
|
Input voltage), and Reference accuracy = DC Voltage accuracy for the |
|
HI to LO (Sense) Reference (in ppm of the Reference voltage). |
Settling Considerations........................................... |
Measurement settling times are affected by source impedance, cable |
|
dielectric characteristics, and input signal changes. |

Gate Times ............................................................. |
Programmable to 1 s, 100 ms, and 10 ms |
Measurement Method............................................. |
Flexible counting technique. AC-coupled input using the ac voltage |
|
measurement function. |
Settling Considerations........................................... |
When measuring frequency or period after a dc offset voltage change, |
|
errors may occur. For the most accurate measurement, wait up to |
|
1 second for the input blocking capacitor to settle. |
Measurement Considerations................................. |
To minimize measurement errors, shield inputs from external noise |
|
when measuring low-voltage, low-frequency signals. |
