 non interlaced video triggering

 smart averaging

 extended offset

MA 190 Accessory Kit

The MA 190 is an optional accessory kit that provides
optimal connectivity to the ScopeMeter test tool in medical
and video applications.

Before use carefully read the 

WARNING

 on page 1-1.

The kit contains:

 TR 190-50R, 50 Ohm BNC feed-through terminator for

video and HF measurements (Max. 5 V) . See Fig. 1-1.

 TA 190-50R, 50 Ohm 10:1 attenuator feed-through

terminator for additional dynamic range and offset.  See
Fig. 1-1.

 CS 190-1R, 1 Ohm current shunt for sensitive current

and mAs measurements. (Max. 500 mA)

 

.  See Fig. 2-1.

 Safety designed 50 Ohm BNC cable with isolated plastic

connectors. (1.5 m)

 Female BNC to male 4 mm banana plug adapter

 Two female to female 4 mm banana plug adapters

Note 1

The

 

CS 190-1R, the TR 190-50R, and the

TA 190-50R are not available as individual
accessory, but only as part of the MA 190 kit.
