Very well might be, let’s find out! Unit received in “unknown” conditions, only tested for power on. Īnd yes, you guessed it, labs got one of these Wavetek 4920M units. Image 2: Datron 4922, photo courtesy AccuSource Electronics. 4920 M has it integrated as standard, replacing mV-module. This external module plugs into option LEMO-type port on regular 4920. There was also standalone wideband module option for 4920, such as Datron/Wavetek 4922 which covers frequency range 10 Hz to 50 MHz. Wideband module to extend input frequency to 50MHz Possible add-on options for Wavetek 4920: Other than that high accuracy main ACV input is about the same for both models and overall operation is same. Differences between the two are listed in Table 2. There are two known modifications of this AVMS, Model 4920 and Model 4920M. Type-N + 5-way Binding posts, shunt input

Type N + 5-way Binding posts, shunt input Let’s take a look on key specifications of high-performance AC standards and compare them to one of the best DVMs – HPAK 3458A.Ģ.2m, 7m, 22m, 70m, 220m, 700m, 2.2, 7, 22, 70, 220, 700, 1000

After Datron/Wavetek instrumentation division acquisition by Fluke in early 2000’s this AVMS was discontinued and replaced by Fluke’s 5790A AC Measurement Standard. Typical customers and users include technicians, engineers, metrologists, medical-device manufacturers, and computer network professionals - people who stake their reputations on their tools, and use tools to help extend their personal power and abilities.Datron (later Wavetek) Model 4920 is AC Voltage measurement standard, which is essentially a high precision voltmeter, but designed with sole goal to perform accurate AC voltage measurements. It designs, develops, manufactures, and sells commercial electronic test and measurement instruments for scientific, service, educational, industrial, and government applications.įrom industrial electronic installation, maintenance and service, to precision measurement and quality control, Wavetek tools help keep business and industry around the globe up and running.
