Rear Panel

The rear view of the Analyzers are represented in the figures below. The rear panel is equipped with the following parts:

• Power cable or power supply receptacle;
• External trigger input connector;
• External trigger output connector (Cobalt models only);
• Reference Frequency input connector;
• Reference Frequency output connector;
• USB 2.0 High Speed receptacle;
• Reserved port (Planar 304/1 only);
• Auxiliary input ports (Cobalt models only);
• Fuse Holder (C1209 only);
• Ground terminal.

Power Cable Receptacle

The power cable receptacle (Planar and Cobalt models) is intended for 100 VAC to 240 VAC 50/60 Hz power cable connection. The power supply receptacle (S models) 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.

External Trigger Signal Input Connector

This connector allows the user to connect an external trigger source. Connector type is BNC female. Planar and S models TTL compatible inputs of 3 V to 5 V magnitude have up to 1 μs pulse width. Input impedance at least 10 kΩ. Cobalt models TTL compatible inputs of 0 V to 5 V magnitude have up to 2 μs pulse width. Input impedance at least 10 kΩ.

External Trigger Signal Output Connector (Cobalt models only)

The External Trigger Signal Output port can be used to provide trigger to an external device. The port outputs 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.

External Reference Frequency Input Connector (Planar and Cobalt models)

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.

Internal Reference Frequency Output Connector (Planar and Cobalt models)

Output reference signal level is 3 dBm ± 2 dB at 50 Ω impedance. «Ref Out» connector type is BNC female.

Reference Frequency Input/Output Connector (S models)

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.

USB 2.0 High Speed

The USB port is intended for connection to a computer.

Reserved Port (Planar 304/1)

Auxiliary input ports (Cobalt models only)

Auxiliary input ports allow the user to input DC signal for DC signal measurement. This is useful in cases where the DUT works on a DC supply and it is required to measure the DC supply along with other measurements of the DUT using the Analyzer.

Fuse Holder (С1209 only)

Fuse protects the Analyzer from the excessive current.

Ground terminal

To avoid electric shock, use the terminal for grounding.
