Network Analyzers using S2VNA software

The power supply receptacle is intended for an external DC power supply voltage from 9 to 15 V; alternatively, the power supply can be powered by a battery, including a vehicle battery, through an appropriate vehicle power cable. All models except the S5180B, S7540, S5243 require a 3.5x1.35 mm plug with positive center conductor for DC connection, the S5180B, S7540 requires a 4-pin power connector (similar to the Kycon KPPX-4P).

The power cable receptacle (S5243 model only) is intended for 100 to 240 VAC 50/60 Hz power cable connection.

The power switch serves as the disconnecting device (device that cuts off power supply) of the VNA. The power supply must be cut off to avoid such danger is electric shock, during prolonged non-use of the device.

This connector allows to connect an external trigger source. Connector type is BNC female. For input and signal parameters, see instrument specification.

The External Trigger Signal Output port can be used to provide trigger to an external device. The port outputs signal with various waveforms depending on the setting of the Output Trigger Function: before frequency setup pulse, before sampling pulse, after sampling pulse, ready for external trigger, end of sweep pulse, measurement sweep. Connector type is BNC female.

In the pulse mode, this connector can be assigned to the following signals (See Pulse Measurements):

•"Ready for pulse trigger" output.

•Internal generator “Pulse 1” output.

•Standard Trigger output.

In standard mode, the connector is used as a Trigger output. The External Trigger Signal Output port can be used to provide trigger to an external device. The port outputs signal with various waveforms depending on the settings of the Output Trigger Function: before frequency setup pulse, before sampling pulse, after sampling pulse, ready for external trigger, end of sweep pulse, measurement sweep. Connector type is BNC female.

In the pulse mode, this connector can be assigned to the following signals (See Pulse Measurements):

•"Pulse trigger" input.

•Internal generator “Pulse 2” output.

In standard mode, the connector is used as a Trigger input. This connector allows to connect an external trigger source. Connector type is BNC female. For input and signal parameters, see instrument specification.

This connector is used in the pulse mode only. Depending on the pulse mode (See Pulse Measurements) the connector is an input of the external pulse modulation signal or an output of the internal pulse modulation signal. Connector type is BNC female.

External reference frequency is 10 MHz, input level is 2 dBm ± 3 dB, input impedance 50 Ω. Output reference signal level is 3 dBm ± 2 dB into 50 Ω impedance. Connector type is BNC female.

External reference frequency is 10 MHz, input level is 2 dBm ± 2 dB, input impedance at «Ref In» is 50 Ω. Connector type is BNC female.

Output reference signal level is 3 dBm ± 2 dB at 50 Ω impedance. Connector type is BNC female.

The USB port is intended for connection to an external PC.

A Fuse protects the Analyzer from the excessive current.

To avoid electric shock, use  this terminal for grounding.

The Ground terminal allows to connect directly the body of the Analyzer to the test station ground in order to ensure electrical safety.

A Kensington lock (K-Slot) is part of an anti-theft system.
