Page 18: Getting Started
Before connecting and powering up the instrument, please review the instructions in this chapter. 4.1 Input Power The 1820B series instruments can be powered by three sources: an internal rechargeable battery, DC input from the supplied AC adaptor, or USB power from a desktop or portable PC. The AC adaptor takes priority over USB or battery power;... -

Getting Started removed. The Power key can be used to turn the instrument on or off while USB power is connected. USB power is available even without using the connection for remote control. 4.1.3 AC Adaptor Operation The AC adaptor connects to the rear panel socket labeled DC IN. When connected, the red EXT POWER LED lights up, indicating power, and the yellow CHARGING LED shows if the battery is charging. -
Page 20: Front Panel Operation
Front Panel Operation At power-on, the power supply will automatically enter the front-panel operation mode and the instrument can be controlled via the front panel keys and knob. Input ................5.1.1 Input A Configuration . -
Page 21: Input
Front Panel Operation 5.1 Input Inputs A, B, or C (1826B only) are selected by pressing the Select Input key, with an indicator showing the active input. 5.1.1 Input A Configuration Input A handles frequencies from 0.001Hz to over 125MHz and offers various configuration options for different waveforms and amplitudes. -
Page 22: Input B
Front Panel Operation 5.1.2 Input B Input B is for frequency measurements from 80MHz to over 3GHz with a nominal 50 impedance. The Ω maximum input voltage is 1Vrms, and the input is diode-clipped for signals over 250mVrms. It is protected against accidental connection to mains voltages up to 250Vrms at 50/60Hz. -
Page 23: Functions
Front Panel Operation 5.2 Functions Functions are selected using the keys located below the display, with annunciators indicating the current settings. Figure 5.1 Function Selection and Annunciator 5.2.1 Input A Function Selection Pressing the Frequency, Period, or Width key sets the instrument to the corresponding function. Holding the key for more than 1 second switches to the secondary function: Count, Ratio, or Duty, with the selected function indicated on the display. -
Page 24: Input B Function Selection
Front Panel Operation 5.2.2 Input B Function Selection With Input B (80MHz–3GHz) selected, only Frequency and Period functions are available. Attempts to select Width Count, or Duty will be ignored, indicated by a brief flash of the B annunciator. Selecting Ratio (by holding the Period key) activates Ratio B:A mode, which compares the frequency of Input B to Input A. -
Page 25: Measurement Fundamentals
Measurement Fundamentals 6.1 Frequency and Period Measurements The instrument uses **reciprocal counting** for measurements. After each gate time, it waits for the current input cycle to finish before capturing the count data. By measuring the total time for a whole number of cycles and dividing it by the number of cycles, it calculates the signal’s average period and derives the frequency. -
Page 26: Accuracy Considerations
Accuracy Considerations 7.1 Internal Oscillator The instrument features an internal temperature-compensated crystal oscillator (TCXO), calibrated to within ±0.2ppm at 21ºC using a Rubidium reference. At temperatures between 5ºC and 40ºC, the additional error is less than ±1ppm. The oscillator’s aging rate is under ±1ppm in the first year and decreases over time. -
