+# Sinara 5633 HV Amplifier
+
+* [Wiki](https://github.com/sinara-hw/HVAMP_32/wiki)
+
+## Setup
+
+1. Connect the HV Amplifier to the Zotino/Fastino with IDC connectors (stand-alone mode) or with mezzanine connectors (meazzanine mode). Be aware of pin alignment when using it in the meazzanine mode
+2. Connect the DC barrel or ATX cable to HV Amplifier but **don't supply power** 
+
+## Testing
+
+After running `artiq_sinara_test` on the connected Zotino/Fastino:
+
+```text
+*** Testing Zotino DACs and USER LEDs.

+
+1. Turn on the external power supply connecting to the HV Amplifier **(⚠️Danger: High Voltage active, don't touch the bare PCB without PPE)**
+2. Probe with multimeter/DC voltmeter each pair of pins from bottom to top (left pins are ground)
+3. Check that respective pins have voltages multipled by the gains as described by `artiq_sinara_test` (e.g. for 5x gain variant 0.1V pin => 0.1V x 5 = 0.5V )
+4. Check LEDs are on
