input with a 50Ω termination. Select leading and

trailing times.

CHECK - The Rise and Fall times measured between 10% and

90% points are within specification.

Amplitude Accuracy Test

SPECIFICATION - ± (1% of setting +10mV)

into 50Ω.

PROCEDURE - Connect the instrument OUTPUT to the oscilloscope

input with a 50Ω termination. Change the high and low

levels to obtain different signal amplitudes.

Select a period of 100us.

CHECK - The signal amplitude measured is within specification.

Internal Trigger Accuracy Test

SPECIFICATION - ± 0.01% from 100ns to 100s.

PROCEDURE - Connect the instrument SYNC OUT to the counter

input A, set to measure period in Auto Trig mode.

Select INT TRIGGER mode on SEFRAM 4451 and change

the rate to different values.

CHECK - The trigger rate measured by the counter is within

specification.

GPIB Capability

Connect the SEFRAM 4451 generator to a controller. Each side of this connection must be fitted with a

proper IEEE-488 interface. Operate the instrument via the GPIB bus and change setting as desired. This

procedure assumes that the operator has some experience in programming the controller and is familiar with

the GPIB standard.
