Operating Characteristics

Operating Characteristics are specified with the Measurement/Storage

Module installed on an Agilent 54600–Series Oscilloscope.

Measurements

Voltage Vamp, Vavg, Vrms, Vpp, Vpre, Vovr, Vtop, Vbase, Vmin & Vmax

Time Delay, Duty Cycle, Frequency, Period, Phase Angle, Rise Time,

Fall Time, +Width, & –Width

Thresholds User-selectable among, 10%/90%, 20%/80% or voltage levels

Cursor Readout Voltage, time, percentage, and phase angle.

Waveform Math Functions Addition, subtraction, multiplication, differentiation,

integration, and FFT.

Fast Fourier Transforms

Test Region Each pixel is selectable to be tested or not.

Inputs On either ch1, ch2, or F1

Freq Cursor Resolution From 1.22 mHz (milliHz) to 9.766 MHz (1.22 mHz to 48.828 MHz

for 54615/54616)

Points Fixed at 1024 for all models except 54615/54616

Fixed at 1024 for 54615/54616 with vectors off

Fixed at 512 for 54615/54616 with vectors on

Peak Find: Find Peak automatically snaps cursor to the two largest peaks

located anywhere in the displayed frequency span.

Measurement information is automatically displayed at the

bottom of the screen together with the difference in

frequency between the two selected peaks.

Variable Sensitivity and

Offset

Sensitivity and vertical offset (position) are controlled from

the front panel to display an optimum view of the spectrum.

Sensitivity is calibrated in dB per divisions; vertical offset is

calibrated in dBV.

Time Record Length 10x main sweep speed.

Horizontal Magnification

and Center Frequency

Control

As the frequency span is changed, the display is magnified

about center frequency so that you get a closer view.
