Description

•    Introducing the DVM Unit MR8990 with high 24-bit resolution! Perform high-speed, high-accuracy measurement without going through a scanner.
•    Support for multi-channel measurement (MR8740: up to 54 ch; MR8741: up to 16 ch)
•    Isolated input (between input channels; input-to-chassis isolation: maximum input-to-ground rated voltage of 300 V AC/DC)
•    High-speed sampling (max. 20 MS/s; with 54-ch type, simultaneous sampling of up to 32 ch)
•    Ideal for rack-mounting (4U height/within 180 mm; display-less, box-type design)
•    Display waveforms and make settings on a DVI-D connected monitor and mouse
•    Remote measurement via LAN using control commands from a PC

* Number of channels:

- Block I - 16 analog units: From 32 ch analog + 8 ch standard logic inputs

- Block I - 13 analog units + 3 logic units: 26 ch analog + 56 ch logic (8 ch standard logic + 48 ch logic unit)

- Block II - 11 analog units: From 22 ch analog + 8 ch standard logic

- Block II - 8 analog units + 3 logic units: 16 ch analog + 56 ch logic (8 ch standard logic + 48 ch logic unit)

* Measurement ranges (20 div full scale):

- 5 mV to 20 V/div, 12 ranges, resolution : 1/100 of range (when using 8966)

- 5 mV to 50 V/div, 5 ranges, resolution : 1/50,000 of range (when using MR8990)

* Max. allowable input: 400 V DC (when using 8966; upper limit voltage that can be applied between input terminals without damage)

* Max. rated voltage to earth: 300 V AC/DC (input and instrument are isolated; between input channels and chassis; upper limit voltage that can be applied between input channels without damage)

* Frequency characteristics: DC to 5 MHz (-3 dB, when using 8966)

* Time axis (MEMORY operation): 5 µs to 5 min/div; 26 ranges; time axis resolution: 100 points/div; time axis expansion: 3 stages from ×2 to ×10; compression: 13 stages from 1/2 to 1/20,000

* Measurement functions: Memory (high-speed recording), FFT

* Memory capacity: 16 MW/ch (fixed), total of 864 MW installed

* Removable storage: USB memory stick (USB 2.0)

* Display: None (1 digital DVI terminal per block, 800 × 600 dots)

* External interfaces: [LAN] 100Base-TX (DHCP and DNS support, FTP server, HTTP server), [USB] USB 2.0 Series A receptacle × 2 (mouse operation)

* Power supply: 100 to 240 V AC, 50/60 Hz (250 VA max.)

* Dimensions and mass: 426 mm (16.77 in) W × 177 mm (6.97 in) H × 505 mm (19.88 in) D, 10.8 kg (381.0 oz) (main unit only)
