7.7 Sourcing Frequency
The calibrator can source a constant pulse signal according to the preset frequency and amplitude.
Step 1:
Using the function selector switch
(FUNC)
, select the frequency source function. The LCD shows the default
frequency value (10 Hz) and the frequency symbol
in the lower LCD area.
Step 2:
Using the
(RANGE)
key, select a frequency range (100Hz, 1KHz, 10Hz, 100KHz). The selected function, the default
range source value, and the unit of measure are shown in the lower area of the LCD.
Step 3:
Set the output value digit by digit using each pair of
〔
S
〕
/
〔
T
〕
output setting keys.
Each pair of
〔
S
〕
/
〔
T
〕
keys corresponds to each digit of the LCD reading. Each press of the
〔
S
〕
/
〔
T
〕
key increases
or decreases the digit. Increasing the digit from 9 or decreasing it from 0 causes the digit to overflow or underflow, allowing
the output value to be set without interruption. Holding down the
〔
S
〕
/
〔
T
〕
key changes the digit quickly. The value won’t
change if it is increased or decreased to the Maximum or Minimum value.
Step 4:
Pressing the
〔
VPEAK
〕
key once switches to the amplitude setting mode. The LCD shows a reading of 1V.
Step 5:
Set the output value digit by digit using each pair of
〔
S
〕
/
〔
T
〕
output setting keys.
Each pair of
〔
S
〕
/
〔
T
〕
keys corresponds to each digit of the LCD reading. Each press of the
〔
S
〕
/
〔
T
〕
key increases
or decreases the digit. Increasing the digit from 9 or decreasing it from 0 causes the digit to overflow or underflow, allowing
the output value to be set without interruption. Holding down the
〔
S
〕
/
〔
T
〕
key changes the digit quickly. The value won’t
change if it is increased or decreased to the Maximum or Minimum value.
Step 6:
To re-enter the frequency set mode and set the frequency, press the
〔
FREQ
〕
key.
Step 7:
Pressing the
(ON)
key causes the SOURCE indicator on the LCD to change from ‘’OFF‘’ to ‘’ON ‘’. The calibrator
sources constant pulse signals between its output terminals according to preset frequency and amplitude.
Step 8:
To switch OFF the output, press the
(ON)
key again. The ‘’OFF‘’ icon appears on the LCD and no signals are
sourced between the terminals.
7.8 Sourcing a Number of Pulses
The calibrator can source a preset number of pulse signal according to the preset frequency and amplitude.
Step 1:
Using the function selector switch (FUNC), select the pulse source function. The LCD shows the default value (10
Hz) and the pulse icon
.
Step 2:
Using the
(RANGE)
key, select a frequency range. The selected function, the default range source value, and the
unit of measure are shown in the lower portion of the LCD.
Step 3:
Set the output value digit by digit using each pair of
〔
S
〕
/
〔
T
〕
output setting keys.
Each pair of
〔
S
〕
/
〔
T
〕
keys corresponds to each digit of the LCD reading. Each press of the
〔
S
〕
/
〔
T
〕
key increases
or decreases the digit. Increasing the digit from 9 or decreasing it from 0 causes the digit to overflow or underflow, allowing
the output value to be set without interruption. Holding down the
〔
S
〕
/
〔
T
〕
key changes the digit quickly. The value won’t
change if it is increased or decreased to the Maximum or Minimum value.
