IWATSU SY-5001A High-Frequency Bipolar Power Amplifier Dedicated Matching for SY-8264

The SY-5000A series linear high-frequency bipolar power amplifier is a world-leadingWideband precision power amplifier.

They are ideal for all applications requiring fast-changing signals under purely resistive and inductive loads. Two selectable operating voltage modes are provided, respectively for high-voltage/low-current and low-voltage/high-current applications. The SY-5001A additionally provides switchable gain factors and automatic offset control. When the load impedance is extremely low, please select the low operating voltage mode to reduce power loss and increase output current. The A model also has a built-in slew rate limiter to achieve more precise square wave signal output. These devices are equipped with temperature-controlled low-noise fans. Over-temperature protection, power loss calculation, and absolute current monitoring ensure comprehensive short-circuit and overload protection. The amplifier can be controlled via the operating elements on the front panel or fully remotely via USB. The SY-5001A can also be remotely controlled via GPIB with SCPI commands.

LED controls for overload/over temperature/hardware error

[1]:  ON / STANDBY Switch to turn the amplifier from standby to „ON“. Switch to standby with output off [3] only. 

[2]:  OUTPUT Power connector for output (±150V / ±10A max.). In „OFF“ state the output is switched to signal ground. 

[3]:  OUTPUT Switch to turn the output „ON“ or „OFF“. The switch lights up when the amplifier is  switched on. 

 [4]:  GAIN The gain switches are used to adjust the overall gain of the amplifier. The LED of the selected amplifi-                 cation factor lights up permanently. Changing the gain triggers an automatic offset adjustment.  

 [5]:  INPUT Signal input (±3V input voltage range), input impedance 50Ω, BNC. 

[6]:  GROUND SOCKET Protective earth connection. 

[7]:  OFFSET ZERO Switch to trigger, an DC offset adjustment. Lights up permanently after successful offset     adjustment, flashes at approx. 1 Hz in the event of an error during the offset adjustment.

 [8]:  OUTPUT VOLTAGE HIGH / LOW Switch to change the output voltage mode from HIGH (±150V) to   LOW (±75V) or vice versa. The LED lights up in HIGH voltage mode. Switch only when output is in idle  state, e.g. deactivated, for amplifier board firmware V1-05 or lower. 

[9]:   PROTECTION Lights up continuously at an overtemperature, flashes slowly (1 Hz) when exceeding maxi mum current limit or permissible power loss, and flashes quickly (3 Hz) at a hardware defect.

[10]   READY Lights up permanently when the amplifier is ready for operation

Applications:

1. High-frequency magnetic material loss analysis
