Substantial Doubt about Going Concern [Text Block]	2 Going Concern and Management’s Plan The Company incurred net losses of $1.5 $4.1 March 25, 2017 March 26, 2016, $25.6 March 25, 2017. The Company has experienced delays in the development of features, orders, and shipments for the new ASG. These delays have significantly contributed to a decrease in working capital from $1.8 March 26, 2016, $620,000 March 25, 2017. To help fund operations, the Company relies on advances under the line of credit with Bridge Bank. The line of credit which expired on May 7, 2017, May 6, 2019 ( 20, March 25, 2017, $582,000, $234,000, These matters raise substantial doubt as to the Company’s ability to continue as a going concern. To address these matters, the Company’s management has taken several actions to provide additional liquidity and reduce costs and expenses going forward. These actions are described in the following paragraphs. ● In July 2016, $1.9 $884,000 2017 nine twelve On April 27, 2017, $1,500,000 April 28, 2017. two 20, ● With the elimination of Giga-tronics Switch, Power Meter, Amplifier, and Signal Generator legacy product lines resulting from the Asset Purchase Agreements with Spanawave and Astronics, (see Note 10, 71 2016 57 2017, 2018. ● In May 2017, May 6, 2019. ● In the first 2016, $10.0 second 2017, 2020. ● To assist with the upfront purchases of inventory required for future product deliveries, the Company entered into advance payment arrangements with certain customers, whereby the customers reimburse the Company for raw material purchases prior to the shipment of the finished products. The Company will continue to seek similar terms in future agreements with these customers and other customers. Management will continue to review all aspects of the business in an effort to improve cash flow and reduce costs and expenses, while continuing to invest, to the extent possible, in new product development for future revenue streams. Management will also continue to seek additional working capital through debt, equity financing or possible product line sales, however there are no The Company’s historical operating results and forecasting uncertainties indicate that substantial doubt exists related to the Company’s ability to continue as a going concern. Forecasting uncertainties exist with respect to the ASG product line due to the potential longer than anticipated sales cycles as well as with potential delays in the refinement of certain features, and/or the Company’s ability to efficiently manufacture it in a timely manner. The accompanying Consolidated Financial Statements have been prepared assuming that the Company will continue as a going concern and do not

Fair Value Disclosures [Text Block]	9 Fair Value Pursuant to the accounting guidance for fair value measurement and its subsequent updates, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. The accounting guidance establishes a hierarchy for inputs used in measuring fair value that minimizes the use of unobservable inputs by requiring the use of observable market data when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on active market data. Unobservable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. The fair value hierarchy is broken down into the three • Level 1 1 • Level 2 2 • Level 3 no The carrying amounts of the Company’s cash and cash-equivalents and line of credit approximate their fair values at each balance sheet date due to the short-term maturity of these financial instruments, and generally result in inputs categorized as Level 1 3 At March 25, 2017 March 26, 2016, zero $379,000, $384,000 March 26, 2016, March 25, 2017 zero 2017.
