# HP 53152A 46 GHz CW Microwave Counter (Pre-Owned) # HP 53152A 46 GHz CW Microwave Counter (Pre-Owned) ## Key Features At A Glance - Frequency coverage from 50 MHz to 46 GHz on a single microwave input (Channel 2) - Simultaneous frequency and power measurement at the input connector via integrated zero-bias Schottky diode sampler - Channel 1 covers 10 Hz to 125 MHz with 25 mV sensitivity (40 mV from 10–30 Hz) - HP-IB (IEEE-488.1/488.2) and RS-232C interfaces standard, with SCPI-1992.0 programming - Backlit LCD display with analog peaking indicator for tuning and peaking applications - Resolution selectable from 1 Hz to 1 MHz; sample rates Fast, Medium, Slow, and Hold - Optional internal battery (Option 002) providing minimum 2.5 hours continuous operation at 25°C - Optional oven timebase (Option 001) for improved aging and temperature stability The HP 53152A is a full-featured CW microwave frequency counter covering 10 Hz to 125 MHz on Channel 1 and 50 MHz to 46 GHz on Channel 2. It is the top-frequency member of the HP 53150 Series, which also includes the HP 53150A (20 GHz) and HP 53151A (26.5 GHz). The series is designed for use in field, factory, and laboratory environments, combining microwave frequency measurement with simultaneous power measurement through a single microwave input connector. According to the datasheet, the HP 53152A is intended for field, bench, and ATE applications. The instrument is described as comfortable in the laboratory while also being rugged enough to tolerate the vibration and shock expected in field use, with a backlit LCD designed for visibility from dark environments to full sunlight at distances exceeding 15 feet. For automated test and benchtop applications, the unit provides full programmability via standard HP-IB and RS-232C interfaces using SCPI-1992.0 commands. ValueTronics International has specialized in professional test and measurement equipment since 1992. Each instrument we sell is inventoried, inspected, and tested in our own 20,000 square foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois — not drop-shipped from a distant broker or passed through an opaque pipeline. This in-house operational footprint is what lets us speak to the actual condition of the specific HP 53152A unit a customer receives, document accessories accurately, and stand behind every transaction with the kind of accountability that a marketplace listing cannot replicate. ## Brand Heritage The HP 53152A originated under Hewlett-Packard's test and measurement division. In 1999, HP spun off its T&M business as Agilent Technologies, and in 2014 Agilent further separated its electronic measurement business as Keysight Technologies. Instruments carrying the HP brand from this product family trace their continuing engineering lineage through Agilent to Keysight. ## Compare Other Models in This Series The HP 53150 Series consists of three CW microwave counters that share a common architecture, form factor, and feature set while differing in upper microwave frequency coverage. All three models share the same Channel 1 low-frequency input (10 Hz to 125 MHz at 25 mV sensitivity), the same standard HP-IB and RS-232C programmability, the same backlit LCD with analog peaking indicator, the same math functions (offset, averaging, cable loss compensation), and the same optional internal battery and oven timebase. The differentiation across the series is the Channel 2 microwave coverage and the corresponding sensitivity profile at the highest frequencies. The series was designed by Hewlett-Packard to provide a single instrument family that could address bench, ATE, and field applications across a broad span of microwave frequencies, with the chosen model determined by the highest frequency the user's measurement environment requires. Each pre-owned HP 53150 Series model linked below is presented on its own product page with condition-matched pricing and an instrument-specific listing. Use the comparison points to identify the model that matches your required frequency coverage, then visit the individual page for current availability, included accessories, and the formal quote. The HP 53152A extends Channel 2 coverage to 46 GHz, the widest in the family. It is the only model in the series with documented sensitivity specifications in the 26.5–40 GHz band (-23 dBm) and 40–46 GHz band (-17 dBm), and it is the only model that uses a 2.92 mm removable connector (SMA and APC-3.5 compatible) on Channel 2. FM tolerance on the 53152A is specified as 20 MHz p-p maximum to 26.5 GHz and 12 MHz p-p maximum above 26.5 GHz at a 10 MHz rate. Acquisition time on Channel 2 is 140 ms in FM Auto mode and 115 ms with FM Off, slightly longer than the 53150A and 53151A reflecting the wider frequency coverage. The three models differ primarily in their Channel 2 upper frequency limit and in the sensitivity, SWR, and power measurement accuracy specifications at the highest covered bands. The HP 53150A covers Channel 2 from 50 MHz to 20 GHz. The HP 53151A extends Channel 2 to 26.5 GHz and adds a -25 dBm sensitivity specification for the 20–26.5 GHz band. The HP 53152A extends Channel 2 to 46 GHz, adding sensitivity specifications for the 26.5–40 GHz (-23 dBm) and 40–46 GHz (-17 dBm) bands and a 2.92 mm removable connector. The comparison table that follows summarizes these differences side by side. Channel 1, programmability, math functions, options (Option 001 oven timebase, Option 002 battery and dc input), and physical dimensions are identical across all three models.
