Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| vna_discoverB | Scan ports 5025-5035 for running VNA instances |
| vna_launchB | Launch VNA software with socket server enabled (Windows only) |
| vna_connectB | Connect to VNA at specified host:port |
| vna_disconnectB | Disconnect from VNA |
| vna_identifyB | Get VNA identification (*IDN?): manufacturer, model, serial, firmware |
| vna_get_statusC | Get VNA connection and configuration status |
| vna_configure_sweepC | Configure sweep parameters: frequency range, points, IF BW, power |
| vna_set_center_spanC | Configure frequency via center and span |
| vna_set_averagingC | Configure sweep averaging |
| vna_set_port_powerC | Set power level per port |
| vna_output_onC | Enable RF output |
| vna_output_offC | Disable RF output (safe state) |
| vna_trigger_sweepB | Trigger single sweep and wait for completion |
| vna_get_s_parameterC | Get S-parameter data (frequencies, magnitude, phase) |
| vna_measure_return_lossA | Measure return loss (S11) at specific frequency |
| vna_measure_vswrC | Measure VSWR at specific frequency |
| vna_measure_insertion_lossC | Measure insertion loss (S21) at specific frequency |
| vna_set_markerC | Position marker at frequency |
| vna_get_markerB | Get marker value (frequency, magnitude, phase) |
| vna_marker_search_minC | Search for minimum value in sweep |
| vna_marker_search_maxC | Search for maximum value in sweep |
| vna_marker_bandwidthB | Find -3dB (or specified) bandwidth around peak |
| vna_calibration_statusC | Get calibration validity status |
| vna_calibration_startA | Start calibration procedure. Automatically disables port extension on all ports before starting (port extension during calibration causes incorrect coefficients). Returns port_extension_was_disabled: true if any ports had extension enabled. |
| vna_calibration_measure_standardB | Measure calibration standard (OPEN/SHORT/LOAD/THRU) |
| vna_calibration_applyC | Apply calibration (calculate and save coefficients) |
| vna_correction_onC | Enable error correction |
| vna_correction_offB | Disable error correction |
| vna_get_port_extensionB | Get port extension settings (delay and loss compensation) |
| vna_set_port_extensionA | Set port extension to compensate for cables/fixtures (delay and/or loss) |
| vna_clear_port_extensionC | Clear/disable port extension for specified port |
| vna_save_touchstoneB | Export S-parameter data to Touchstone file (.s1p/.s2p/.s4p) |
| vna_save_screenshotB | Save VNA display screenshot |
| vna_software_hideC | Hide VNA software UI |
| vna_software_showC | Show VNA software UI |
| vna_scpi_sendA | Send raw SCPI command (no response) |
| vna_scpi_queryC | Send SCPI query and return response |
| vna_resetB | Reset VNA to default state (*RST) |
| vna_presetC | Preset VNA (SYST:PRES) |
| vna_list_templatesA | List available measurement template presets |
| vna_load_templateC | Load measurement template (preset name or file path) |
| vna_apply_templateC | Apply loaded template configuration to VNA |
| vna_save_stateB | Save current VNA configuration to file |
| vna_load_stateC | Load and restore VNA configuration from file |
| vna_get_full_stateC | Get complete VNA configuration state as JSON |
