• Temperature Units: Select the desired temperature units (degrees
Celsius or degrees Fahrenheit).
• Signal Level Units: Select the units to be used for checking signal
power levels (dBmV, dBuV, and dBm).
• Frequency Tuning Step Size: Adjust the Tuning Step Size using the up
and down diamond keys or the numeric entry keys (0.01 to 100.00 MHz
