Start Freq Press this soft key to set the start frequency in units of Hz, kHz, MHz, or GHz. If you enter a start frequency that is higher than the currently‑set stop frequency, and if CAL = On, then the start frequency is set to the same value as the stop frequency. If you enter a start frequency that is higher than the currently‑set stop frequency, and if CAL = Off, then both start and stop frequency are set to the new frequency. Stop Dist Press this soft key to set the stop frequency in units of Hz, kHz, MHz, or GHz. If you enter a stop frequency that is lower than the currently‑set start frequency, and if CAL = On, then the stop frequency is set to the same value as the start frequency. If you enter a stop frequency that is lower than the currently‑set start frequency, and if CAL = Off, then both stop and start frequency are set to the new frequency. Center Freq Press this soft key to set the center frequency in units of Hz, kHz, MHz, or GHz. The center frequency can be set with the arrow keys, the rotary knob, or the number keypad. When using the number keypad, the menu displays soft keys with Hz, kHz, MHz, and GHz units. Pressing the Enter key has the same effect as pressing the MHz soft key. Span Press this soft key to set the span in units of Hz, kHz, MHz, or GHz. The span setting determines the frequency range over which the instrument sweeps. The span may be set from 0 (zero) to the maximum frequency of the instrument. Gate Press this soft key to display the Gate Menu. Domain Setup Press this soft key to return to the Setup Domain Menu. The message on the key face reflects the setup feature (Distance) that is in use. |
Gate Function Off Display On Press this soft key to toggle the Gate Function status to Off, Display, or On. When set to Off, the gate is not displayed on the screen nor applied to the data. When set to Display, the gate shape is displayed on the screen but the gate filtering is not applied to the data. When set to On, the gate shape is displayed on the screen, and the gate filtering is applied to the data. Start Gate Press this soft key to set the start Gate value. The values will be in units of time if the active trace is in the Time Domain, or in units of distance if the active trace is in the Distance Domain. Use the arrow keys, the rotary knob, or the number keypad to set a Gate value. When using the number keypad, the menu displays soft keys with seconds (s), milliseconds (ms), microseconds (µs), nanoseconds (ns), or picoseconds (ps), if in the Time Domain. Otherwise, it displays meters (m), centimeters (cm), or millimeters (mm) as units, if in Distance Domain. Pressing the Enter key has the same effect as pressing the seconds (s) soft key or the meter (m) soft key. If the Application Options Menu (VNA Mode) menu is used to set units in feet rather than meters, then the distance settings are in feet (ft) only, and pressing the Enter key sets the units to feet. Stop Gate Press this soft key to set the stop Gate in either time or distance units, depending on whether the active trace is in the Time Domain or the Distance Domain. In time domain, the units are in seconds (s), milliseconds (ms), microseconds (µs), nanoseconds (ns), or picoseconds (ps). In distance domain, the units are in meters (m), centimeters (cm), or millimeters (mm). If the Application Options Menu (VNA Mode) menu is used to set units in feet rather than meters, then the distance settings are in feet (ft) only. |
Center Gate Press this soft key to set the center Gate in either time or distance units, depending on whether the active trace is in the Time Domain or the Distance Domain. In time domain, the units are in seconds (s), milliseconds (ms), microseconds (µs), nanoseconds (ns), or picoseconds (ps). In distance domain, the units are in meters (m), centimeters (cm), or millimeters (mm). If the Application Options Menu (VNA Mode) menu is used to set units in feet rather than meters, then the distance settings are in feet (ft) only. Span Gate Press this soft key to set the span Gate in either time or distance units, depending on whether the active trace is in the Time Domain or the Distance Domain. In time domain, the units are in seconds (s), milliseconds (ms), microseconds (µs), nanoseconds (ns), or picoseconds (ps). In distance domain, the units are in meters (m), centimeters (cm), or millimeters (mm). If the Application Options Menu (VNA Mode) menu is used to set units in feet rather than meters, then the distance settings are in feet (ft) only. Gate Notch On Off Press this soft key to turn On or Off the Gate Notch feature. When Gate Notch is set to OFF, the polarity of the Gate is set to keep everything between start and stop. When the Gate Notch is set to ON, the polarity of the Gate is set to reject everything between start and stop. Gate Shape Press this soft key to open the Gate Shape Menu. The Gate Shape value is displayed on the key face, and may be Minimum, Nominal, Wide, or Maximum. Back Press this soft key to return to the previous menu. |
Minimum Press this soft key to set the gate shape value to Minimum. Nominal Press this soft key to set the gate shape value to Nominal. The Nominal gate shape is the default value and most commonly used one. Wide Press this soft key to set the gate shape value to Wide. Maximum Press this soft key to set the gate shape value to Maximum. Back Press this soft key to return to the previous menu. |
Window / Gate | Minimum | Nominal | Wide | Maximum |
Rectangular | OK | OK | OK | OK |
