3.5 Basic Operations
3.5.1 Simplified Sweep Measurement
This section describes simplified operations when first using
FRA5022
.
It describes as frequency sweep and a measurement of a system's frequency response.
Proceed according to the following procedure.
1) Initialization: executed to simplify understanding of the following steps.
2) Setting the measurement conditions
3) Sweep measurement
4) Measured values reading
■
Initialization
・
Press the MENU/EXIT key to display the menu screen.
・
Use the Left/Right cursor keys
△ ▽
to move to the system menu

screen.
・
Use the Up/Down cursor keys to select INITIALIZE all.
・
Press the key 1 to initialize.
■
Setting the measurement conditions
・
Use the Left/Right cursor keys
△ ▽

screen.
・
Set the values as below for example.
AC Amplitude OSC ac amplitude 1.00Vrms Set the value with the ENTR key
DC bias OSC dc bias 0.00V Set the value with the ENTR key
Integration time MEAS integ. time 0.10s Set the value with the ENTR key
Integration cycle MEAS integ. cycle 1c Set the value with the ENTR key
Frequency max SWEEP freq. max 100.00kHz Set the value with the k key
Frequency min SWEEP freq. min 10.000Hz Set the value with the ENTR key
Automatic scaling DISP scale Auto
After measurement, the vertical scale is
automatically selected.
For the possible settings range, check the comments in the lower side of the screen.
・
Press the ON AC/DC OSCILLATOR key to turn the oscillator's output on.
The oscillator's output voltage will not change by only modifying the setup value. It is
changed by this procedure.
■
Sweep measurement
・
Press the Measurement DOWN or UP key.
The screen changes to Sweep measurement screen and the measured gain and phase
are displayed as a graph (Bode diagram).
■
Measured values reading
・
Use the Left/Right cursor keys
△ ▽
to move the graph's frequency data cursor
(vertical line), the measured value at the position of the cursor is displayed as a
numerical value.
