Front and Rear Panel Overview
Figure 1-1 shows the front and rear panels of the Keysight 53210A 350 MHz RF
Counter.
Front Panel
The shaded areas of the front panel represent keys that perform similar functions.
These areas are briefly described below.
A. Measure Keys - display soft key menus from which the measurement function
is selected. Auto Scale senses the input signal (greater than 100 Hz) on input
channel 1, 2, or 3 and automatically sets the range and input threshold required to
make the selected measurement. Counter measurements are covered in
Chapter 3.
B. View Keys - select how measurement data is displayed on the front panel.
Display configuration is covered later in this chapter. Graphics, math, and data
logging are covered in Chapter 6.
C. System Keys - provide instrument-wide configuration which includes setting
the counter preset state and access to utility functions and to the counter’s
built-in help system. For measurement configuration involving numeric entry,
Shift changes the key definitions to the numbers at the lower left of the keys.
D. Channel Keys - select the input channel and displays the soft key menu used
to configure the input signal path. Note that Figure 1-1 includes Channel 3 Option
106 / 115. Signal path configuration is covered in Chapter 4.
E. Gate and Trigger Keys - select the gating and triggering soft key menus used
to control the measurement. Gating and triggering are covered in Chapter 5.
F. Soft Keys - are the menus from which the counter is configured. The menus
and soft keys themselves are defined by the “functional” keys described above.
G. Power/Standby Button - switches the instrument between ‘on’ and ‘off’, or
between ‘on’ and ‘standby’.
